Mod_Rewrite Detection in PHP for Apache and IIS

Mod_Rewrite, a powerful tool for URL rewriting, can be utilized on both Apache and IIS. However, determining if it's enabled in PHP presents challenges, especially for IIS.

Apache Detection

If using mod_php, one can leverage the apache_get_modules() function to obtain a list of enabled modules. Subsequently, checking for mod_rewrite involves:

in_array('mod_rewrite', apache_get_modules());

IIS Detection

CGI typically complicates the process of detecting mod_rewrite on IIS. Nonetheless, a shell command can be employed:

strpos(shell_exec('/usr/local/apache/bin/apachectl -l'), 'mod_rewrite') !== false

If this condition evaluates to true, mod_rewrite is enabled on IIS.
