Question

zeroise( int $number,  int $threshold )

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.
