PHP files have to be set to "execute" in Linux/unix. The "permissions map" is 3 sets of octal numbers, as follows:

-rwxrwxrwx

Where the first set is the file owner's permissions, the second set is the group permissions, and the 3rd set is the "world" permissions. The RWX's relate to the octal values like this:

-421421421

So 755 = Owner: rwx, group, rx, word, rx

If you don't have EXECUTE permission set, you cannot run a script/program.

syntax: "chmod 755 filename"

You can see the r/w permissions by executing an "ls -l filename" command.

Hope that helps
