I only know about chmod 777, chmod 644,...etc and I am trying to chmod folders or files with

Code: 
chmod a-w filename.php
This command is what I read from a web hosting article but they didn't explain me in detail.

Can any one tell me What is chmod a-w?

Many thanks!

Here is the description for you -

chmod is the command which will change the permission of the files.

a stand for all possible users (u+g+o). o stands for ‘others', not ‘owner'.

w is for change or delete a file, or add or delete a directory's contents

CHMOD a-w means that you remove all writing privileges (from any group).
