问题
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 php function just like we list php information with phpinfo(); function?
回答1:
On Debian:
user@machine:~$ /usr/sbin/apache2 -l
Most GNU/Linux distros:
user@machine:~$ /usr/sbin/httpd -l
Ubuntu:
user@machine:~$ ls /etc/apache2/mods-enabled
On Mac OSX:
user@mymac:~$ httpd -l
On Win 7 (64-bit):
C:\Users\myuser>"\Program Files (x86)\Apache Software Foundation\Apache2.2\bin\httpd.exe" -l
Try these commands from a terminal window in all but Windows, which will use CMD instead.

All the above answers are wrong. Use instead:
apachectl -t -D DUMP_MODULES
or
apachectl -M

On Ubuntu you can see the list of enabled modules here,
/etc/apache2/mods-enabled
回答4:
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/');
