Add leading zeros

[Arkane]

Just a quick one (I think).  I have data being pulled from a database, including a number field.  Problem is, this field is just the number, whereas I need to have it in a 4dp mode.

 

I just need a quick way to add leading zeros, so that the number will always be length 4.

ie 1 = 0001, 23 = 0023, 456 = 0456

Anyone able to help me?

<?php
$str = sprintf('%04d', 1); // 0001
?>

 

or use printf() if you just wish to output it instead of assign it to a string.
