How to check if mod_rewrite is enabled in php?
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.
I like Christian Roy's solution:
### .htaccess
<IfModule mod_rewrite.c>
# Tell PHP that the mod_rewrite module is ENABLED.
SetEnv HTTP_MOD_REWRITE On
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# The rest of your rewrite rules here
</IfModule>
Then, you can check in your PHP code for
array_key_exists('HTTP_MOD_REWRITE', $_SERVER);
No idea if this works also with IIS (I have no way to check) but the odds are good.
Copy this piece of code and run it to find out.
<?php
if(!function_exists('apache_get_modules') ){ phpinfo(); exit; }
$res = 'Module Unavailable';
if(in_array('mod_rewrite',apache_get_modules()))
$res = 'Module Available';
?>
<html>
<head>
<title>A mod_rewrite availability check !</title></head>
<body>
<p><?php echo apache_get_version(),"</p><p>mod_rewrite $res"; ?></p>
</body>
</html>
