PHP shell_exec and running as apache? how to grant access to some of the filesystem?

Hi all,

I need to run the following PHP line:

echo shell_exec('/root/visitors_0.7/visitors -A -m 30 -o html /var/log/httpd/access_log');
I know apache runs as user 'apache' on my server and currently it gives me "permission denied" errors because all the files are owned by root.

What's the best way of giving permission to just these files so it can run?

Or perhaps there is a better way?

Here's my setup:
cloud server on rackspace

ls -lh ~/visitors_0.7/
-rwxr-xr-x 1 root root 264K May 15 20:34 visitors

ls -lh /var/www/html/s/
-rw-r--r-- 1 root root 224 May 16 23:16 index.php

You can set uid permissions on that script but your best option would be to use suphp.

suphp does indeed look good - thank you kind sir.

Compiling a setuid() C program works like a charm, and this is my short term solution.
