• How to filter a two dimensional array by value 4 answers

I want to remove all elements from arr2 that have a type contained in arr1:

    arr1 = ['A', 'B', 'C']

    arr2 = [
        [
        'name' => 'jane',
        'type' => 'X'
        ],
        [
        'name' => 'jon',
        'type' => 'B'
        ]
    ]

So jon should be removed. Is there some built in function like array_diff?

One of solutions using array_filter:

print_r(array_filter(
    $arr2, 
    function($v) use($arr1) { return !in_array($v['type'], $arr1); }
));
