$first=array(1,2,3,4);
$second=array(1,2,3,5);
$result1=array_intersect($first,$second);
while (list ($key, $val) = each ($result1)) {
echo "$key -> $val <br>";
}0 -> 1
1 -> 2
2 -> 3 Example 2
$first=array('One' =>1,'Two'=>2,'Three'=>3,'Four'=>'Fourth');
$second=array('One'=>1,'Two'=>2,'Third'=>3);
$result1=array_intersect_assoc($first,$second);
while (list ($key, $val) = each ($result1)) {
echo "$key -> $val <br>";
