Simple PHP URL rewrite

One thing I did for dmb is making dodosmb.com/profile/username work with my profile.php script. Normally without the help of .htaccess, you can use the value of the path info from the global variable

$_SERVER['PATH_INFO']

For example, create a php file named profile.php and in there put:

<?php echo $_SERVER['PATH_INFO']; ?>

Then upload the file and load it with yourServerPath/profile.php/dodo. The script will print out

/dodo

In my profile.php, I get the user by doing a simple sub string command like:

$user = substr($_SERVER['PATH_INFO'], 1); // this will get rid of the leading slash

This allows me to feed users to my profile.php by using the url dodosmb.com/profile.php/username

That’s still not pretty enough; it’s better if I can do dodosmb.com/profile/username. This is where .htaccess rewrite comes in. Here’s a great tutorial for .htaccess rewrite rules. To accomplish my goal, I used the following rewrite rules in my .htaccess:

RewriteEngine on
RewriteRule ^profile/([A-Za-z0-9]+)/$ /profile.php/$1
RewriteRule ^profile/([A-Za-z0-9]+)$ /profile.php/$1

  1. I’m about to develop a php based website and I found your thread.
    Thank god that’s exactly what I’m looking for! :heart:

  2. Some comments/suggestions on your URL rewrite code. You have duplicates in the list for with and without a slash.


    RewriteEngine on
    RewriteRule ^profile/([A-Za-z0-9]+)/$ /profile.php/$1
    RewriteRule ^profile/([A-Za-z0-9]+)$ /profile.php/$1

    It is easier if you simply make the slash optional using a regex question mark following the slash. This eliminates the need for two rules to do the same thing.


    RewriteEngine on
    RewriteRule ^profile/([A-Za-z0-9]+)/?$ /profile.php/$1

    Also, it may be necessary to enable the FollowSymLinks option to get the server to actually do the rewrite. You would add the following to the top of the .htaccess to be sure it was enabled.


    Options +FollowSymLinks

    So, if you followed both suggestions, your new .htaccess would look like this.


    Options +FollowSymLinks
    RewriteEngine on
    RewriteRule ^profile/([A-Za-z0-9]+)/?$ /profile.php/$1
