TheUsual/PHP exists to provide a fast, free, user-friendly web browser viewing and maintenance interface for MySQL databases. It runs on your own computer under a web server like Apache or IIS, on a dedicated intranet or internet server, or on a remote hosting server (dedicated or shared) running MySQL 5 or up and PHP 5.5 or up.
There is one current version of TheUsual/PHP, for the mysqli PHP API. (The mysql PHP API is disappearing from PHP; the last version of TheUsual for the mysql PHP API was 1.90.)
TheUsual implements the Artful concept of TheUsual—a clean, efficient, intuitive web interface for doing the jobs you usually have to do to create, update, populate, maintain and query databases, their objects and tables and data.
Chapter 12 of Get it Done with MySQL 5&Up, excerpted here, outlines the basic design and approach.
To download TheUsual/PHP, visit https://www.artfulsoftware.com/theusual.html and scroll to the bottom of the page.
Pre-5 PHP used MySQL the version 3.x client module. This is no longer supported.
The mysql PHP API is obsolete. The last upgrade of TheUsual/PHP for that API, theUsualPHPmysql.rar, was version 1.90. Use the mysqli API instead, and the version of theUsual for that API, theUsualPHPmysqli.rar.
PHP and MySQL authentication: Since v5.5, MySQL has supported
authentication plugins, and version 8.0 has made
pluggable authentication the default, but ...
caching_sha2_passwordor the MySQL 8.0 default plugin,
mysql_native_password, so these PHP versions can't use
caching_sha2_passwordand for the MySQL 8.0 default authentication plugin
mysql_native_password. In any PHP version, phpinfo.php (or the function
phpinfo()) lists supported authentication plugins under "Loaded plugins" in entries whose names begin with
Users of TheUsual are responsible for acquiring and remembering their MySQL login credentials. It's not in TheUsual's brief to intrude on MySQL user access management; TheUsual's job is to remember securely hashed passwords for one or more host/user pairs and make those hashes available for validation against a submitted login password. As of v2.5.0 it uses the PHP functions password_hash(), password_verify().
MySQL-PHP configuration has many moving parts. If you're not using one of the many package webdev installations (LAMP, WAMP, XAMPP &c), these are the best guides we know for getting them to work together:
Windows with Apache web server:
Windows with IIS
As of v2.5.0, installation has been streamlined.
Step 1: Unpack the archive. Create a folder named theusual off the Document Root of your web server. Document Root is usually something like /var/www, /apache24/htdocs, home/your_site_name/public_html, or under IIS on Windows c:\inetpub\wwwroot. Into this new theusual folder, unpack theUsualPHPmysqli.rar preserving path info. That will yield...
Of these files. the following manage authentication ...
user@host => hashed_passwordvalues generated by the PHP function
password_hash()to be inspected by function
host, user, pswdvalues so they can be read directly by TheUsual in contexts where more security is not needed
Step 2: Move the include files. If this is a new installation of TheUsual, or if your previous TheUsual version was pre-2.5.0, move the files in the unpacked includes installation folder into a folder that is in PHP's include_path, or to an includes folder outside the Document Root, e.g., to /var/includes if Document Root is /var/www/, to /home/your_site_name/includes/ if Document Root is /home/your_site_name/public_html, to /apache24/includes/ if Document Root is /apache24/htdocs/, and so on.
If this is an upgrade of TheUsual from version 2.5.0 or later, you can delete the unpacked includes files
Step 3: Simplest authentication. Most simply but least securely—e.g., if you are installing TheUsual on a private web server on your own well-secured development machine—you may want to forego a login dialog and write login specs directly into includes/theusual-login.php, e.g., ...
<?php $_SESSION['host'] = getenv( "php_host" ) ? getenv( "php_host" ) : "localhost" ; $_SESSION['user'] = getenv( "php_user" ) ? getenv( "php_user" ) : "myusername" ; $_SESSION['pswd'] = getenv( "php_pswd" ) ? getenv( "php_pswd" ) : "mypassword" ; ?>In your browser run localhost/theusual/theusual_start.php, bookmark the page, then login. You're up and running.
Step 4: More secure authentication. If you are installing TheUsual on a public web server, you do not want to be writing plaintext passwords anywhere on the server—you need better security than Step 3 provides. Visit https://php-password-hash-online-tool.herokuapp.com, click on PASSWORD HASH, enter your MySQL password, copy the result, and follow instructions at the top of includes/theusualinc.php to paste in the hash result along with your MySQL 'host@username' value. For multiple MySQL users, repeat for each user.
In your browser run YOUR_HOST_URL/theusual/theusualauth.php, bookmark the page, then login. You're up and running.
Alternatives: We're in the open source ecosystem so naturally you're free to replace step 3 or 4 with any other authentication scheme you please. If you're doing this, please remember ...
sha256_passwordauthentication plugin nor the MySQL 8.0
$_SESSION['host'], $_SESSION['user'], and
$_SESSION['pswd']settings that TheUsual can use to connect to MySQL.
If you are running TheUsual on IIS:
1. Be sure to enable read-write sharing for IIS_IUSR for TheUsual's folders and subfolders.
2. Since Windows 7, IIS authentication is byzantine. If PHP scripts like TheUsual fail with an error like "You do not have permission to view this directory or page because of the access control list (ACL) configuration ...", from Start run inetmgr, click on the top level in the left navigation panel, select Authentication in the IIS middle panel, right-click on Anonymous Authentication and select Edit, and in the resulting Edit Anonymous Authentication Credentials dialog, click the Application pool identity radio button. Incredible, but there it is.
3. To allow imports bigger than 30MB, try this: select the top item in the left inetmgr navigation pane, click on Request Filtering in the middle pane under IIS, select Hiodden Segments, right click on Web.Config, from the context select Edit Feature Settings, and change Maximum Allowed Content Length to a value that suits your needs. Then restart IIS. If IIS doesn't allow big uploads, you will have to FTP or otherwise copy them directly into TheUsual's uploads folder.
The script theusualcall.php puts up dropdown menus for multiple installed instances of TheUsual and of available MySQL servers.
It uses the text configuration file includes/theusualcall.ini, which may have two kinds of configuration lines, one kind for instances of TheUsual and one for available instances of MySQL server ...
1. For each available installation of TheUsual:
one line of comma-separated
path for one installation of TheUsual ...
theusual= your choice of name for this instance of TheUsual, perhaps for example its version number and/or the name of the machine it's running on; this will be the name by which this instance of TheUsual is selected in the menu.
groupcan access only MySQL database servers with the same
groupname (e.g., you couldn't run a local instance of TheUsual against a web MySQL instance on the same parameters you use for local instances)
host= LAN machine name or URL for accessng this instance of TheUsual
path= path at
hostto the PHP script that invokes this installation of TheUsual, typically either ...
/theusual/theusualauth.phpto bring up a login dialog, or
Example: Suppose you have two local installations of TheUsual, and one on a remote web site ...
theusual=thelaptop, group=lan, host=thelaptop, path=/theusual/theusualauth.php.. unless you write a custom login script for any of those installations.
theusual=thedesktop, group=lan, host=thedesktop, path=/theusual/theusualauth.php
theusual=thewebsite, group=wan, host=https://thewebsite.com, path=/theusual/theusualauth.php
Attacks on web servers are getting smarter, so is browser security.
Best practice now is to enable SSL on all web servers including
one's own private and presumably secure development server; for all such servers,
LAN and WAN, server
host will begin with
2. For each distinct MySQL user login, one line of comma-separated
key=value pairs specifying the MySQL server name and its server group.
Optionally, if the MySQL server is entirely private and secure, this line can also have
login username and password, though that's not recommended ...
mysql= the name of this MySQL server; if it is on your LAN, this is that machine's name; if on the web, it is the MySQL server host name specified by the hosting provider; this is the naame that theusualcall.php will show for this instance of MySQL,/li>
group= the name of the group to which this MySQL database server belongs; installations of TheUsual with a given
groupname can access only MySQL database servers with the same
Theusualcall.php ignores lines in theusualcall.ini that don't begin with 'theusual' or 'mysql'. See the sample includes/theusualcall.ini.
TheUsual maintains its metadata---settings, saved queries, input form plugins,
non-transactional master-detail table relationships---in MySQL tables. TheUsual's
startup script theusual_start.php stores the name of the database for these tables,
theusualsys, in a PHP session array element
If the MySQL login you are using for TheUsual includes the
privilege, you need do nothing to make this work---TheUsual will create the
theusualsys database when it finds the metadata database missing.
(Until MySQL version 5.7, we could use 'sys' as the default name of the metadata database.
MySQL 5.7 implemented its own sys database, so we changed the default name to 'system'.
MySQL 8.0.3 made 'system' a reserved word, so since theUsual v2.18, the name
is what it should have been all along,
If the MySQL login you are using for TheUsual doesn't include the
privilege---as on a shared hosting account where databases must be created in other software
like cPanel---you'll need to create a database for TheUsual to use for these tables,
then edit theusual_start.php to set
$_SESSION['sysdb'] to the name of your
If you have access to just one database and no privileges to create other databases,
$_SESSION['sysdb'] in theusual_start.php to the name of your
one database; TheUsual will create and maintain your metadata tables in your one database.
Any number of the same or different instances of TheUsual can run simultaneously in browser tabs, because TheUsual implements the session setup described in Chapter 12 of Get It Done With MySQL 5&6 and under MySQL and PHP | Basics | Session setup at https://artfulsoftware.com/infotree/mysqltips.php
On load, TheUsual offers a list of databases for which you have privileges. Once you select a database, TheUsual puts up a dropdown table selection list, and a saved queries dropdown for the current database if the theusualsys database has been initialised and if there are saved queries.
Once you click the Select button for a choice from the Table dropdown, TheUsual brings up a paged datagrid display of that table with order-selectable headers, and a navigation bar permitting selection of rows-per-page and the Top/Previous/Next/Bottom page of data. When the table is editable (that is, it has a primary or unique key), each row has prompts for adding, editing, adding using a copy of ther current row, or deleting.
If the selected table uses an ACID-compliant storage engine like InnoDB, and if other tables in the current database have foreign keys referencing that table, the navigation bar offers a dropdown detail table selector. If you select a detail table from that dropdown, TheUsual displays a second grid with detail rows matching the current row of the master table. If that child table is in turn the pmaster or arent of another table, Go commands in that grid select that detail table as the master table in a refreshed page.
Clicking on the Metadata link brings up a table browser for the current schema with Analyze, Check, Export, GoTo, Optimize, Repair and Drop options. GoTo has the same effect as selecting that table or View from the Table/View dropdown. In v2.31 the SQL formatter function (originally from GitHub) was revamped to make it more useful for reading the vast amounts of interesting Stored Routine and View code that MySQL provides since v5.7 in its sys database:
Per page: A rows/page dropdown selector appears on the dashboard when the query is pageable. Possible values are 1,2,5,10,20,50,100,500,1000,2000,5000. To change these, edit $pagelens in theusual.php.
Prev, Top, Next, Last: Display the previous, top, next or last <per page>
rows returned by the current query. These prompts default to arrow icons but can be set to
Top Prv Nxt Bot in Settings.
Detail table: This is a dropdown selection list of ACID-compliant tables in the currently selected database with a foreign key referencing the currently selected table. Up to version 1.89, TheUsual could display one master-detail table relationship. Since version 2.00 (mysqli version only), there is no limit to the number of cascading master-detail relationships.
Master-detail relationships without declared foreign keys: Some MySQL and MariaDB storage engines do not support foreign keys, yet management of data in such tables often needs master-detail logic. TheUsual helps with this by letting you add, to the above child tables list, master-detail table relationships without declared foreign keys. It does this by storing such table relationship specifications in a theusualfks table in the metadata database.
If TheUsual does not find such a table, it creates it. You can use TheUsual (or any other MySQL client) to add rows to this table specifying master-detail (parent-child) table relationships.
TheUsual documents master-detail relatonships in the same way MySQL
information_schema documents foreign keys. To create a non-InnoDB master-detail
relation for a pair of tables, insert rows in the theusualfks table where the
Referenced schema, table and column document the parent table, and the
remaining three columns document the child table, as in this example for a MyISAM version
of the MySQL
world database ...
When you browse world.country in TheUsual, you can choose city or countrylanguage as a child table, and TheUsual will auto-generate dropdown picklists for the relevant foreign keys...
Beware that TheUsual does not (yet) validate parent-child entries in theusualfks table; it just tries to execute them as if they were real foreign keys, and reports an error if the specification is incorrect.
If the detail table itself has a detail table, the leftmost column of each detail row shows, in addition to Edit, Ins, Copy and Del options, a Go option that makes the current detail table the master table in the next browse, which will be of the page containing the selected row. Use Go to daisy-chain down any number of cascading master-detail table pairs.
The navigation bar GoTo control goes to the first page on which it finds a value
matching a column search value the user has entered. It's enabled for a base table or a View
selected from the Table dropdown. Up to v2.01, it supports primary key searches. Since v2.02, select
a column from the dropdown that appears, then enter a value to search for: if TheUsual finds a
first instance of that column value on the current ordering, it will display that page. Since
v2.03, if the column value you enter contains the '%' wildcard, TheUsual will look for
a column value LIKE your search value. (To find multiple instances of a value,
use Query, with parameters if desired (see below), to add a
to the current query.)
When the table has a primary or unique key, each row offers options to Edit, Ins(ert), Copy or Del(ete) that row. Clicking on Edit puts the current row in edit mode, clicking on Ins brings up a new row for editing, and clicking on Copy brings up a new row which is a copy of the current row for editing. Finish an Edit, Ins or Copy cycle by clicking Save or Cancel.
As of v2.36, the Settings page has an item specifyng the number of columns a table must have to switch the format of the Edit/Ins/Copy form from in-table rowwise horizontal to vertical showing just one row. The default is 5. If you set it to 0, the Edit/Ins/Copy format will always show just one row or record vertically. If you set it to a number greater than the greatest number of columns you have in a table, the Edit/Ins/Copy form format will always be in-table rowwise horizontal.
Automatic foreign key lookup dropdowns: Since v1.57, during row edits, for columns that are foreign keys in ACID-compliant tables, and also for TheUsual's user-defined foreign keys, TheUsual automatically puts up a dropdown for selection of a key value from the referenced table. In that dropdown, beside the key column, it also displays a (VAR)CHAR description column, if it can find one. You can tell TheUsual what description column to use if you enabled TheUsual's user-defined foreign keys: edit the theusualfks table in the database specified by $_SESSION['sysdb'] = 'admin', and in the row for that foreign key, set the value of the column named referenced_desc_column to the desired SELECT expression (beware: TheUsual doesn't verify your syntax!).
Plugins for forms
Version 1.85 introduced input form plugins. This feature needs the
Install an input form plugin by adding a row to that table specifying coltype, onfocus, jsfile and cssfile, and optionally specify script and onblur.
As a demonstration example and as a convenience, if the
table is empty and if TheUsual can find the files calendar.js and
calendar.css in the current folder, it installs a calendar popup plugin for
date inputs by creating and populating a theusualplugins
row for it. To import some other plugin, bring up the theusualplugins
table in TheUsual, add and populate a row.
MySQL since 5.0 implements Views, so theUsual/PHP treats Views as tables. To create a View, run a CREATE VIEW statement as a custom query. To execute a View, select it from the Tables dropdown.A single-table View is editable on the same criteria that MySQL uses to determine editability. Columns of the main table of a multi-table View are editable on the same criteria.
MySQL Views have their limitations. They tend to be slow; indeed executing queries retrieved from a saved queries table is up to twice as fast as executing a View that invokes the query. And before MySQL version 5.7.7, Views may not have FROM clause subqueries, which multi-table reports often need.
So TheUsual can save custom queries in a
theusualviews table in its
theusualsys database, and it retrieves such queries from
that table for editing and execution.
Saved queries are enabled unless theUsual finds its environment hasn't allowed creation of a saved queries table ...
CREATE TABLE theusualviews ( name VARCHAR(64) PRIMARY KEY DEFAULT '', db VARCHAR(64) NOT NULL DEFAULT '', User VARCHAR(16) NOT NULL DEFAULT '', Host VARCHAR(64) NOT NULL DEFAULT '%', qry VARCHAR(8192) NOT NULL DEFAULT '', changed TIMESTAMP );
Once the saved queries table is present, a Save button appears on the custom query form. Once at least one saved query exists for a given database, a Query: prompt and dropdown appear beside the Table: prompt and dropdown at the top of the page when that database is selected. The custom query module supports multiquery scripts, so it can be used not just to run queries in the conventional sense, but also to run SQL script jobs (less than about .25MB; see below for how to run larger import scripts).
To manage your saved queries, select the database where it is, then select theusualviews from the Tables dropdown, browse and edit the saved queries table as you would for any other table. For editing of non-trivial queries it's usually much more efficient to copy to your preferred text editor, edit the query script there, then paste back into theUsual's interface for the saved queries table.
Selecting Query from the navigation dashboard brings up a resizable custom
query text control and an Execute button. With a saved queries rable present,
there is also a query name control and a Save button. It supports
CREATE PROCEDURE | FUNCTION | TRIGGER, for each of which, if the
routine consists of multiple statements, you'll need to specify an alternative
delimiter before, e.g.,...
DELIMITER go CREATE PROCEDURE... BEGIN ... END; go DELIMITER ;
Multi-query results: The mysqliAPI supports multiple resultsets, so TheUsual shows them all even when they're from a stored procedure call in a multi-query script.
Runtime query parameters: As of v2.36, the Custom
Query module supports query parameters which the user fills in at runtime before the query
executes. Mark such parameters with the string
including the surrounding square brackets. For example, if you often need to search
a documents table
items( id int, author varchar(128), txt text ) for entries
with text containing a certain word or character sequence, you could save a custom query ...
select * from items where txt like '%[theusual_query_param]%';When asked to execute this query (either saved, or entered raw), theUsual will put up a form prompting for a paramater value ...
and once the user has entered a
theusual_query_paramvalue to search for, it will substitute that value into the query, then execute it. You can specify any number of parameters.
Load Data Infile: Since version 2.47 TheUsual has a user-friendly
Load Data Infile queries. It's invoked both for standalone Load Data
queries and for Load Data queries occurring in multi-query scripts.
The wrapper supports runtime query parameters so, for example, if a query begins with...
LOAD DATA INFILE '[theusual_infile_param]' INTO ...... and if the system variable
secure_file_privnames an available input file folder, then before executing that query, TheUsual will show the query to the user with a dropdown file selector replacing
[theusual_infile_param], and will substitute the user's selection into the query unless she cancels.
Load Data query runs against an
InnoDB table, TheUsual
runs the query asynchronously so during execution it can report the
count by polling
Show Engine InnoDB Status at intervals on another connection;
by default it spits out a reporting line for each chunk of 10M bytes. With transactional and
non-transactional tables alike, it reports warnings and errors.
Big query scripts, Import
Do not try to send scripts with more than about 0.25MB of SQL text through Query. The custom query module is meant for scripts that are small enough to be meaningfully interactive and which may display SELECT results; it bogs down with more than 250 KB of input, and depending on the browser, can grind to a halt near 1MB.
For query scripts > 200KB in length use the Import command in the navigation bar. The import module can process 30MB of SQL commands on ordinary hardware in a minute. The Import option brings up a form where the user may ...
The Import module creates its uploads folder if it does not exist, logs file uploads to theusual_uploads.txt, and logs upload errors to theusual_uploads.err. If the import file is too big to be uploaded through the browser (e.g., the IIS 7.5 limit is 30MB unzipped, and difficult to change), you'll need to FTP or otherwise copy the SQL command file directly into the uploads folder.
The module can handle files that contain SQL text; it can also handle zip, gzip, bzip2
and rar SQL archives. Most PHP installations support zip and gzip. Bzip2 needs PHP configuration
--with-bz2. (The PECL rar module was unstable in PHP 5.2 through 5.4---if
you find a rar plugin that works with those PHP versions, please let us know). The import form
also sets sql mode, character set, file deletion policy, and whether to try to determine that the
file actually contains SQL before executing any commands from it.
Beware that several php.ini settings govern import/download file size and script execution
time: edit php.ini, or invoke
ini_set(), to set
to limits that accommodate your largest and longest imports, and
upload_max_filesize to zero if you can live with no limits, or to values
you can live with.
The internet wasn't designed to display results of long batch jobs in real time. The MySQL client program isn't so good at the job either: results fly by faster than they can be read. The Import module is meant to handle potentially huge Inserts, so it shows just the first 80 characters of each SQL command it executes, along with the result. Even with that, screen output may be massive. How will a web browser respond?
Browsers do their own output buffering. We've no control at that level.
Under Apache, output_buffering in php.ini is determinative; it defaults to 4KB, so theUsual uses flush commands keep the user informed about how execution is proceeding.
But under IIS, screen output is usually held back until script execution completes. A Microsoft engineer offered this lame explanation: "For performance reasons and interoperability with some ASP.NET features ... we entirely buffer responses < 1MB and then send them at once." In IIS 7.5 it's actually 4MB. A 30 MB SQL script may take a minute or more to execute. Leaving the user uninformed for that long is rude, but IIS Manager offers no access to the controlling variable. A recommended workaround for this bit of IIS stupidity is first, in the left panel of IIS Manager, create an IIS "web site" forTheUsual, called, say, theUsual_mysqli; second, in the central IIS Manager panel find the name of the PHP engine--say it's PHP52_via_FastCGI; then finally, run this command ...
%windir%\system32\inetsrv\appcmd set config "theUsual_mysqli" /section:handlers /commitPath:apphost -[name='PHP52_via_FastCGI'].ResponseBufferLimit:0... substituting your values for theUsual_mysqli and PHP52_via_FastCGI. Restart IIS.
A Chart prompt appears on the dashboard if TheUsual can match the data in the current datagrid to a type of chart it knows how to draw. TheUsual can now display, on the fly, nine kinds of Google Visualisation API charts—Area, Histogram, Line, Smoothed Line, Motion, Org (Tree), Pie, Pie with Percentages, and Scatter. These charts can use [VAR]CHAR, numeric and DATE values; BLOB, TEXT, ENUM and SET values are ignored. When customising queries for these charts, remember that MySQL functions like FORMAT() return strings; to make strings usable as numeric values for a chart, use CAST( FORMAT(...) AS DECIMAL[...]).
YYYYQn, or a string specifying year weeks in
YYYYWnnformat; and at least one numeric result column. See the example below.
To draw a chart, TheUsual has to write out the data to be charted in a format that the Google Visualization engine can understand, so charts work best with aggregating queries that keep down the rowcount. Area charts, Histograms and Scatter charts can handle up to 10k rows; Org charts can handle 5k rows but are best with a few hundred at most; Line charts can handle 2k rows. Pie charts become unreadable with much more than a dozen rows, though the module will accept 50.
Here is a simple GNP-By-Continent query on the world database:
And here is an image of a minimum motion chart in its final state. All we had to do was ...
Motionfrom the Chart dropdown in TheUsual, then click the Trails checkboxes and the Play button:
select floor(population/100000)*100000 as 'Population Band', count(*) as Size from world.city where countrycode='GBR' group by 1;
Print: Version 1.44 introduced a Print option to send browsed data to the printer of your choice.
Refresh: If your most recent custom query added or dropped a database or table, use this option to refresh the Database and Table dropdown menus.
The Metadata prompt in the navigation bar browses all objects in the currently selected database. Each base table and View gets a row with a GoTo option to browse it; base table rows also have Analyze, Check, Optimize, Repair, Drop options. Below base tables and Views, all stored routines including Triggers are listed with their source code. The Metadata page's navigation bar has Backup, Import, MySQL Error Log (since v2.49), Settings prompts.
MySQL Error Log: Since v2.49, this option displays the MySQL error log, most recent entries first. if the log is available to be read. Note that in some shared hosting sites, and in some organisations, the MySQL error log is not available to some users.
Settings Panel: Since v2.37, this panel supports custom settings for each theusual user. Access the form by clicking Metadata in the navigation bar for any database , then click on Settingsin the Metadata page's navigation bar.
Panel options include setting the default charset, the no. of table columns that triggers a vertical rather than horizontal/tabular form for data input, and the maximum blob size to display; and toggling text/blob formatting, HTML tag stripping from input queries, displaying live urls in text data, and using information_schema for metadata (this latter provided because with MySQL before 8.0, the more databases and tables there are on the server, the slower information_schema is; the first information_schema access can take minutes on servers with dozens of databases and thousands of tables). Each option is described in mouseover tooltips. These per-user settings are maintained in the
theusual_settingstable in the theusualsys database. When you upgrade from an earlier version of theUsual, any settings found theusual_start.php are written to the
Backup: Since v1.45, database backup is available in the database administration browser. It assembles, then offers for download, a file of SQL commands to recreate the tables, views, data, stored routines and Triggers of the current database. It writes its file to the current web folder, offers to download the file to the client, logs the file operation, and when the downlaod completes, it deletes the dump file. If the download is declined or if it fails, the file stays on the server.
Under Apache this is routine. Under Windows and IIS, it can require two additional steps: make the server folder's security tab visible, then use the Security tab to enable writes to wwwroot. Open My Computer, click on Tools | Folder Options and then on the View tab. At the bottom of the list uncheck 'Use simple file sharing (Recommended)'. Now Windows Explorer shows the Security tab in the Properties context menu for every folder. In Windows Explorer, right-click on wwwroot, select the Security tab, select the Internet Guest Account ([username]/IUSR_[username]), check Write and Modify, and press OK.
