Compare two arrays, is there common elements between the two arrays?

Question

I need to test if one element of an array is in another array.

$array_one = array("gogo", "blabla", "toto");

$array_two = array("stackov", "renaul", "toto");

I would like to know if one element of array_one is in array_two ???

How to test that? Am trying in_array but it seems to have problems.

Answer 1

array_intersect()

$array1 = array("gogo", "blabla", "toto");
$array2 = array("stackov","renaul","toto");

$commonElements = array_intersect($array1,$array2);

var_dump($commonElements);
