Is there native function to automatically put specific number of zeros based on actual and maximal value?

Is there any native PHP function which would allow me to do this?

开发者_开发知识库

$number = functionName(1, 9999); // $number == 0001
$number = functionName(10, 99); // $number == 10
$number = functionName(10, 999); // $number == 010

If there isn't native function, is there any user-based function?

echo str_pad($value, strlen($max), "0", STR_PAD_LEFT);

for example

$value = 10;
$max = 999;
echo str_pad($value, strlen($max), "0", STR_PAD_LEFT);
// returns 010

See http://ideone.com/KPBV2 and str_pad()

use str_pad its easy! here's the doc

Not exactly, but you can write one easily using str_pad and its pad_type of STR_PAD_LEFT.

There sure is: str_pad()

<?php
    echo str_pad(33, 5, "0", STR_PAD_LEFT);
    echo str_pad(1, 5, "0", STR_PAD_LEFT);
    echo str_pad(1258, 5, "0", STR_PAD_LEFT);
    echo str_pad(89965, 5, "0", STR_PAD_LEFT);
?>
