I was wondering if it is possible to check if mod_rewrite is enabled on Apache AND IIS in PHP.

ModRewrite for IIS exists. Check it here.

So, I'm looking for a PHP script that checks for mod_rewrite on Apache and IIS.

Does anyone know such script or can write one?

Especially for Microsoft IIS.

Thanks!

If you're using mod_php, you can use apache_get_modules(). This will return an array of all enabled modules, so to check if mod_rewrite is enabled, you could simply do

in_array('mod_rewrite', apache_get_modules());

Unfortunately, you're most likely trying to do this with CGI, which makes it a little bit more difficult.

You can test it using the following, though

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

If the above condition evaluates to true, then mod_write is enabled.
