Changing file permissions (chmod) without SSH/telnet access

If you need to change file permissions (chmod) for more than just a few files and your web hosting provider gives you only FTP access to your account (neither SSH/telnet nor a good web hosting control panel system), you can use the chmod function available in PHP.

You can either write a PHP script that calls chmod for each file that needs its permissions to be changed or use this snippet to call chmod recursively and change permissions for an entire folder tree.
