Making number format like 0001, 0002

In this tutorial, we'll make number format like 0001, 0002, 0003 in stead of 1, 2 ,3. It's very easy to do this. Look at script, we use "printf" in stead of "echo" and ("%04d", $num) This mean show number in 4 digit. You can change number in any digits as you want by replce "4" in "%04d" with number of digit you want.

Overview

For testing this code in this tutorial, we create 1 file
1. number_format.php

Code

<?php

$num = 1;
printf("%04d", $num);

?>

// Result = 0001
