Código PHP:

<?php
 
$array1 = array( 2, 2, 3, 5, 7, 13);
$array2 = array( 2, 3, 3, 7, 11, 13);
 
$intersec = array_intersect($array1,$array2);
 
foreach ($array1 as $key=>$val)
    if(in_array($val,$intersec)){
        unset($array1[$key]);
        unset($array2[array_search($val,$array2)]);
        echo "Eliminando $val ..<br/>";
    }
