cgi chmod problem

I've got a php script that checks certain file permissions and if not OK for writing, chmods as required. I can use ftp_site(); but, prefer not to because the code is not readily transportable. Requires ftp login. I'd like a simple cgi file that can be called by my script as needed. My cgi file works OK if I call directly in my cgi-bin directory. e.g.,

$file= '/EditPage/test2.php'; $perms= 0746;

if(!file_exists($pfile)) echo "<div style=\"color:red; font-weight:bold\">$pfile does not exist.</div>"; chmod($pfile, $perms); echo "New file permissions for $pfile: ". substr(sprintf('%o', fileperms($pfile)), -3);

But, I can't get the cgi file to execute when using "include /path/perm.cgi". in the php test function. I guess it is because the cgi assumes it is running in the directory with the php that called it. Linux php3.9.11 virtual host Anyone have a suggestion.
