Pad Numbers In PHP

·
Free Resource
Sometimes I need numbers to always be two digits, even if they're less than 10. The below snippet will format all numbers to be two digits, inserting a 0 if they're under 10 - creating, for example, 09 instead of 9.


$raw = 1;
$formatted = sprintf("%02d", $raw);
echo $formatted;

//outputs 01
