rand(01,29) not (1,29). how ???

[swiss73]

Hi.

I want to echo a random number 01 to 29.

I can't rename the files as left-1.jpg to left-29.jpg.

they have to stay as left-01.jpg to left-29.jpg

who can help with this?

I searched but did not find how to format numbers in php

[code]
$i = rand(1,29);
if(strlen($i)==1) $i = '0'.$i;
[/code]
