Yes there are solutions to your problem!
The first solution is server dependend. I am a little unsure how this works on an IIS server but it's quiet simple in Apache. Apache can take directives from a file called .htaccess. The .htaccess file needs to be in the same folder as your active script to work. It also needs the directive AllowOverride All
and the module mod_rewrite
loaded in the main server configuration. If you have all this set up you need to edit your .htaccess file to contain the following
RewriteEngine on
RewriteRule ^mywebsite/([^/\.]+)/?$ index.php?user=$1 [L]
This will allow you to access mywebsite/index.php?user=12
with mywebsite/12
.
A beginner guide to mod_rewrite.
You could also fake this with only PHP. It will not be as pretty as the previous example but it is doable. Also, take into concideration that you are working with user input so the data is to be concidered tainted. The user needs to access the script via mywebsite/index.php/user/12
.
<?php
$request = $_SERVER['REQUEST_URI'];
$request = explode($request, '/'); // $request[0] will contain the name of the .php file
$user[$request[1]] = $request[2];
/* Do stuff with $user['user'] */
?>
These are the quickest way I know to acheive what you want.
