Write a PHP function that returns the lowest integer that is not 0

Introduction

PHP is a server scripting language, and It is a powerful tool for making interactive and dynamic Web-pages. I have used WampServer 2.2 for following excercise..

<?php
function min_values_not_zero(Array $values) 
{
return min(array_diff(array_map('intval', $values), array(0)));
}
print_r(min_values_not_zero(array(-3,4,6,12,-300,-1,7))."\n");
?>

Result

Write a PHP function that returns the lowest integer that is not 0
Write a PHP function that returns the lowest integer that is not 0
