/* Pad Numbers in PHP
 
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;
$formatted = str_pad($raw, 2, 0, STR_PAD_LEFT);
echo $formatted;
 
//outputs 01
