Answer 1

$result = !array_diff($arrayA, $arrayB);

Answer 2

Something like this maybe?

<?php
$array1 = array("a" => "green", "red", "blue", "red");
$array2 = array("b" => "green", "yellow", "red");
$result = array_diff($array1, $array2);

print_r($result);

Array
(
    [1] => blue
)
?>

just a rough idea,

<?
$arrayA=array(1);
 $arrayB=array(1,2,3); 
 $k=array_intersect($arrayA,$arrayB);
 print_r($k);
?>
