[Question] Matching an array in PHP

[ev0]

Basically i want to take an array of numbers let's say:

 

<?
$array1=array("1","2","3","4");
?>

 

Now say i reprint that same array, but the 3 is missing.

 

<?
$array2=array("1","2","4");
?>

 

How would i print what's missing from $array1 out of $array2?

 

Sorry if this is confusing, i'll be happy to go into details if needed.

<?php
$arr1 = array(1, 2, 3, 4);
$arr2 = array(1, 2, 4);

$difference = array_diff($arr1, $arr2); // Returns all values from arr1 that are not present in arr2

print_r($difference); // Array(0 => 3)
?>

Oh wow, there really was a function already for that  :'(

 

Thanks a ton!
