I have this array and i want to compare each key items with each other and get similars with array_intersect . I wrote this code but it just compare first 2 key items and i want to compare all of key items.

            $res_arr = array_shift($m);

            foreach($m as $filter){

                $arr = array_intersect($res_arr, $filter);

            }

My Answer:
To compare all key items in the array and get the similarities using `array_intersect`, you can modify your code as follows:

php
$res_arr = array_shift($m);
foreach($m as $filter){
$res_arr = array_intersect($res_arr, $filter);
}

print_r($res_arr);


This code will compare each key item in the array with the previous result array `$res_arr` and update `$res_arr` with the similarities. This way, you will get the similarities between all key items in the array.
