Use array_intersect() to find common elements and array_diff() to find the differences.

Here's my test code:

$array1 = array("red", "blue", "green", "violet");
$array2 = array("yellow", "orange", "violet", "blue");

$uniq_arr1 = array_diff($array1, $array2);
$uniq_arr2 = array_diff($array2, $array1);
$common_arr = array_intersect($array1, $array2);

Play with the code for a bit, you will begin to understand how it works.
