PHP sprintf gives incorrect integer value

I'm trying the following code:

<?php
$test = "326101347676";

echo sprintf("%014d\n", $test);

But it's giving me 00002147483647 output.

What I expect is 00326101347676

I know it's causing by the sprintf function, but I don't know why, could you please help me to solve this problem.

FYI: I'm in PHP/5.3.0

Note: The referred post didn't help me to solve the problem, besides I already tried the bcmod command and didn't go well with my code. Now @devpro last snippet in the comment section working well for me.

If I run your script the output is exact "00326101347676". With PHP 5.5.9-1ubuntu4.14 – PKeidel Feb 02 '16 at 12:52
script returns the correct value in PHP5.3 - 7.0.2, see https://3v4l.org/DBKjS – thgs Feb 02 '16 at 12:55

@thgs Don't you see anything special about `2147483647` number? – raina77ow Feb 02 '16 at 12:57

Compare `echo PHP_INT_MAX;` with your number `326101347676`. The value range of an int/long in your php environment is probably -2147483648 to 2147483647, while 3v4l's version uses 64bit int/longs -> INT_MAX=9223372036854775807 – VolkerK Feb 02 '16 at 12:57
@VolkerK Oh yes, you're right of course. damn 32 bit... – PKeidel Feb 02 '16 at 12:59
Yup I just saw it, you are all right: 2147483647 is PHP_INT_MAX for his machine :) – thgs Feb 02 '16 at 12:59
OK, so who is going to run to write this as the answer :-) – trincot Feb 02 '16 at 13:00
$test = 326101347676; echo sprintf('%s%02s', '00', $test); – devpro Feb 02 '16 at 13:09

$test = 326101347676; echo str_pad($test, 15, '0', STR_PAD_LEFT); // with str_pad – devpro Feb 02 '16 at 13:10
