Array compare

[sandy1028]

Hi,

 

Two arrays

 

 

array_1=array(A,B,C);

arry_2=array(A,A,B,B,A,B,A,B);

 

 

How to find out the element which is not in arry_2.

 

Here in the above example the element should show as C.

Here's one way using the array_unique() and the array_diff() functions:

<?php
$array_1=array('A','B','C');
$array_2=array('A','A','B','B','A','B','A','B');
$array_3 = array_diff($array_1,array_unique($array_2));
echo '<pre>' . print_r($array_3,true) . '</pre>';
?>
