Question

I have this array lets call it array 1

Array
(
    [0] => Array
        (
            [Machine] => Array
                (
                    [id] => 7
                    [name] => XYZ
                    [priority] => 1
                )

            [Software] => Array
                (
                    [id] => 472
                )

        )

    [1] => Array
        (
            [Machine] => Array
                (
                    [id] => 6
                    [name] => ABC
                    [priority] => 0
                )

            [Software] => Array
                (
                    [id] => 470
                )

        )

    [2] => Array
        (
            [Machine] => Array
                (
                    [id] => 1
                    [name] => IEU
                    [priority] => 3
                )

            [Software] => Array
                (
                    [id] => 471
                )

        )

)

Then I have another array lets call it array 2

Array
(
    [0] => 7
    [1] => 5
    [2] => 4
    [3] => 3
    [4] => 6
)

If array 2 doesnt have [Machine][id] then I want it to be removed from array 1. Like in above example 1 will removed

   [2] => Array
            (
                [Machine] => Array
                    (
                        [id] => 1
                        [name] => IEU
                        [priority] => 3
                    )

                [Software] => Array
                    (
                        [id] => 471
                    )

            )

any idea on how to achieve that. Thanks

try something like :

$new_array = array();
foreach ($array1 as $platform)
{
     if (in_array($platform["Machine"]["id"], $array2))
     {
         $new_array[] = $platform;
     }
}

return $new_array;
