# of digits


briant

Recommended Posts

Should be simple but I can't seem to find what the function is called.

I want a number like 1 to have 5 digits, like 00001. Or a number like 528 to be 00528.
Theres a long way to do it like if id is 1 digit add 0000 but then that takes too long and I'm sure there is a function out there.

Thank you

Printf is the same as sprintf so prehaps have a read of how to use [url=http://www.php.net/sprintf]sprintf[/url] function.

printf will do what you want to to do from what I can tell from your thread.
[code=php:0]// an unformated number:
$num = '523';

// now we format it, so it is a 5 digit number with
// zeros at beginning to pad the number to be five digits
$num = printf("%05d", $num);

// print our new formated number:
echo $num;
// the result should be 00523[/code]
