Say you have the number 6 but need to make sure it is 4 digits and out put like: 0006. How would you go about this? One way to do this is the following:

<?php
function zerofill ($num,$zerofill) {
while (strlen($num)<$zerofill) {
$num = "0".$num;
}
return $num;
}
?>

The usage of this code would be:

<?php echo zerofill(6, 7); ?>

Output will be 00006

Keep Enjoying..
