There are multiple methods available how to add or remove leading zeros before number.

To add leading zero before number, you can use sprintf(). The following function will add leading zero before a single digit number:

To remove leading zeros before number, you can use ltrim() or (int):

$value = ltrim($number, "0");
$value = (int)$number;
