Formatting a number with leading zeros in PHP?

Question

I have a variable which contains the value `1234567`. I would like it to contain exactly 8 digits, i.e. `01234567`. Is there a PHP function for that?

Answer 1

You can use str_pad to do this.

<?php

$number = "1234567";

$number = str_pad($number, 8, "0", STR_PAD_LEFT);

echo $number;

?>

As long as your number is less than 8 digits, it will append 0s to it.
