[SOLVED] Left padding 0's

[Ninjakreborn]

If I have a random set of numbers (perhaps some characters).

I need to take.

$variable = 'whatever';

And pad the variable with 0's up to 10.  When it's over with if they variable has below 10 characters, it need's to add zero's up until it has a total of 10 characters.  THe 0's need to add on the left hand side, any advice?

you'll have to make it a string and use http://uk2.php.net/manual/en/function.str-pad.php

Use the sprintf() function:

<?php
$str = "4nc9";
$padded_str = sprintf("%010s",$str);
echo $padded_str;
?>
