The first two thing I would check:
What user is PHP running under? If it's spawned by Apache, it is likely running as "nobody", "www" or "apache" depending on the version and configuration.
What directory are you trying to list? Check the permissions on that directory. Does the user PHP is running as have permission to access that directory?

I'm trying to track down a php issue with a tool that I'm trying to install, and have tracked it down, I believe, to a permissions issue with the filesystem, I believe...
I now have the following simple .php file:
php system("/bin/ls"); ?>When I run this, I see the following error in /var/log/httpd/error_log:
If I change the php to run:
php system("/bin/env"); ?>Then I see the output that I was expecting.
So it's not the execution that doesn't have permissions, it's what the executable is trying to read that is having problems.
(The tool I am trying to get working here is phplicensewatcher - a tool for keeping an eye on what is going on with various license management daemons)
Thanks
