Array_intersect () PHP filter Two elements common to an array

We've already talked about how to filter out elements that are not common in the array, so let's see how PHP filters out the elements that are common to two arrays, such as filtering $array1 and $array2.

Function name: Array_intersect ();

Call mode: Array_intersect ($array 1, $array 2);

Example :

<?php
$array 1 = Array ("A" = "green", "Red", "blue", "grey");
$array 2 = Array ("b" = "green", "yellow", "red");
$result = Array_diff ($array 1, $array 2);

echo "<pre>";

Print_r ($result);

Result: $result = Array ("Green", "red");
?>

Note : The returned result is an array form, and the key value is a number.
