php url shortening

问题

Ok i guess this is a bit of a general question really as opposed to a problem.

I am building a system where users can share their profile on other websites so i am wondering is it possible to shorten the actual url which would provide a link to their profile which would be something like this, www.somedomain.com/users/profile.php?user=myusername to simply cut out the users folder and the profile page and so something like this: www.somedomain.com/myusername

I have seen lots of url shortening scripts but they don't seem to do this, any suggestions or advice would be appreciated.

Thanks

What you're looking for is called URL rewriting and can be done using Apache's mod_rewrite. You would place a file called .htaccess in your root web directory and it would contain a snippet like this:

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule  /(.*) /users/profile.php?user=$1

this is called "url rewriting" - there are different approaches to do this, for example using apaches mod_rewrite. another way would be to manually parse $_SERVER['REQUEST_URI'] - this would make your site work even if mod_rewrite isnt enabled, but is some more work.
