PHP Make Directory with Leading ZERO's

Question

Currently, This is the code I have in place to make a directory in my "members" folder dynamically every-time a user registers on my site.

        $directory = "../members/".$id;
        mkdir($directory, 0755);

The above code works fine but it doesn't name the folder with "0". Example:

When the folder is created in the members directory, It is named 15" in fact is should be named "000000000015".

Guys any idea how to achieve this in php.

Answer 1

use sprintf()

$directory = "../members/".sprintf('%012s',$id);
mkdir($directory, 0755);
