how can i compare an array values with subarray values

Question

I try to get the differences between two arrays I have one big array with subarray and a small simple array. I want to get the difference from the big array.

I use this to get the differences between 2 arrays, but working with subarray is someting else. $array3 = array_diff($bigArray, $smallArray);

$smallArray = Array
(
    [0] => 2  (how i compare this values)
    [1] => 3  (how i compare this values)
)

$bigArray = Array
(
    [0] => Array
        (
            [g_id] => 2  (with this value)
            [g_nume] => Arad I Betel
        )

    [1] => Array
        (
            [g_id] => 3  (with this value)
            [g_nume] => Arad IV Agape
        )

    [2] => Array
        (
            [g_id] => 4  (with this value)
            [g_nume] => Frumuseni
        )

    [3] => Array
        (
            [g_id] => 7  (with this value)
            [g_nume] => Cuvin
        )
)

And the result to be like this:

Array
    (
        [0] => Array
            (
                [g_id] => 4  (with this value)
                [g_nume] => Frumuseni
            )

        [1] => Array
            (
                [g_id] => 7  (with this value)
                [g_nume] => Cuvin
            )
    )

And the code you have written to try and do this for yourself is .......? — RiggsFolly, Oct 30 '18 at 13:29

<?php

$disard_ids = [
    '2', '3'
];

$items = 
[
    [
        'id'=>'1'
    ],
    [
        'id'=>'2'
    ],
    [
        'id'=>'3'
    ],
    [
        'id'=>'4'
    ]
];

foreach ($items as $item) {
    if(array_search($item['id'], $discard_ids) === false) {
        $result[] = $item;
    }
}

var_export($result);

Output:

array (
    0 => 
    array (
    'id' => '1',
    ),
    1 => 
    array (
    'id' => '4',
    ),
)

Check what result the OP says they want and then see your result! – RiggsFolly Oct 30 '18 at 14:04
@RiggsFolly it is a similar enough example is it not? – Progrock Oct 30 '18 at 14:07
