Apache：0777目录上的权限被拒绝

Question

I have shell script, that goes like:

#!/bin/bash
( cd /var/qwebirc; ls .git; )

And PHP file that executes the script:

error_reporting(E_ALL);
exec("/var/qwebirc/pull.sh 2>&1", $arr);

Then when I call the shell script directly, I get the output I expect (ls of .git). When I call the PHP script from CLI, I get the very same output. But when the php script is called from browser, I get

ls: cannot open directory .git: Permission denied

Okay, obviously permission problem of apache user. So I set 0777 to .git and all its files (for testing purposes). chown and chgrp to apache. Changed the script like:

( cd /var/qwebirc; pwd; whoami; ls -dl .git; ls .git; )

But the output in browser is still:

[0] => /var/qwebirc
[1] => apache
[2] => drwxrwxrwx. 8 apache apache 4096 Mar  1 03:59 .git
[3] => ls: cannot open directory .git: Permission denied

Which doesn't make much sense to me. Any idea what's the problem? Thanks.

So the answer is SELinux. Not exactly sure how its policies work (gotta look into that now), but after disabling SELinux, ls from apache started to work.
