You're looking for the str_pad function.
http://www.php.net/str_pad
$i = 3;
$i = str_pad($i, 5, '0', STR_PAD_LEFT);
echo $i; // outputs '00003'
Just keep in mind that it won't help you if your input is greater than 5
to begin with, you'll have to check that seperately.
$j = 123456;
$j = str_pad($j, 5, '0', STR_PAD_LEFT);
echo $j; // outputs '123456'
