Detect if Mod_Security Is Installed With PHP?

Question

Is there any simple way to detect if mod_security is installed & enabled using just PHP? Ideally without any exec() terminal type commands to be executed.

Some people have recommended using apache_get_modules() but this specific web-host does not allow it to show. This is also mentioned by other users here: http://www.devcomments.com/apache_get_modules-solution-to130703.htm

Answer 1

Try the apache_get_modulesfunction to get an array of the loaded modules. If that module is loaded but not listed there, you might want to try phpinfo with phpinfo(INFO_MODULES) instead:

ob_start();
phpinfo(INFO_MODULES);
$contents = ob_get_clean();
$moduleAvailable = strpos($contents, 'mod_security') !== false;
