It will only add the zero if it's less than the required number of characters. When working with numbers, you should use %d (rather than %s ), especially when there is the potential for negative numbers. If you're only using positive numbers, either option works fine. For example: sprintf("%04s", 10); returns 1000 sprintf("%04s", -10); returns 0-10 Where as: sprintf("%04d", 10); returns 1000 sprintf("%04d", -10); returns 100 <? php $num = 4 ; $num_padded = sprintf ( "%02d" , $num ); echo $num_padded ; // returns 04 ?> You can use sprintf: http://php.net/manual/en/function.sprintf.php .
