Question

我试图得到两个数组之间的差异我有一个带有子数组的大数组和一个小的简单数组。我想从大阵列中获得区别。

我用它来获取2个数组之间的差异，但是使用子数组则有些麻烦。 $ 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
        )
)

结果如下：

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

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

<?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);

输出：

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

我如何比较数组值和子数组值
