[thelist] PHP: display leading zero

[Steve Cook]

sprintf should do what you want.
http://www.php.net/manual/function.sprintf.php


You're looking for - sprintf("%02d", $your_string); // to format a string

- or to print directly printf("%02d", $your_string); // notice printf
instead of sprintf!

Hope that helps.
