Add leading zeros when necessary.

Description

If you set the threshold to ‘4’ and the number is ’10’, then you will get back ‘0010’. If you set the threshold to ‘4’ and the number is ‘5000’, then you will get back ‘5000’.

Uses sprintf to append the amount of zeros based on the $threshold parameter and the size of the number. If the number is large enough, then no zeros will be appended.

Parameters

$numberintrequired

Number to append zeros to if not greater than threshold.

$thresholdintrequired

Digit places number needs to be to not have zeros added.

Return

Source

function zeroise( $number, $threshold ) {
	return sprintf( '%0' . $threshold . 's', $number );
}
