My .htaccess file contains:
Options +FollowSymlinks
RewriteEngine On
RewriteRule projects$ projects.php
RewriteRule projects/$ projects.php
RewriteRule projects/page/([^/]*)$ projects.php?page=$1
RewriteRule projects/page/([^/]*)/$ projects.php?page=$1
RewriteRule projects/company/([^/]*)/$ projects.php?companyid=$1
RewriteRule projects/company/([^/]*)$ projects.php?companyid=$1
RewriteRule projects/([^/]*)$ projects.php?id=$1 [L]
It was working fine, but suddenly this section is not working in my website.
This should redirect to "projects.php?companyid=$firstvariable", but actually, I don't know why.
I tried restarting my PC and deleting temp and restarting WAMP.
After some interactive troubleshooting with OP, it appears that WAMP's Apache/PHP will execute a PHP file that matches the directory portion of the URL path if it exists, before applying the .htaccess RewriteRules.
In other words, if you have a file named Abc.php, and you request /Abc/def, WAMP's Apache/PHP will just execute Abc.php and not consult the .htaccess file.
I'm not sure if this is something special about WAMP and whether it's out-of-the-box behavior. I can't find any documentation on being able to control/change this behavior.
