How to check mod_headers and mod_expires modules enabled in apache

Question

I want to check whether mod_headers and mod_expires modules enabled or not in my server

Is there a way available to list apache enabled/disabled modules using some p

Answer 1

Some versions of PHP/Apache show all loaded modules in phpinfo() under "Loaded Modules".

Speeve's answer shows compiled in modules (x6 on my system):

echo system('/usr/sbin/apache2 -l');

You'll also need to see your enabled modules (x36 for me):

echo system('ls /etc/apache2/mods-enabled/');

To get the list of disabled modules, run this command then cross off all the enabled modules:

echo system('ls /etc/apache2/mods-available/');
