Question

我有两个这样的多维数组： Guest允许数组

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

和第二个像这样

   Array
(
    [0] => Array
        (
            [property_id] => 6
            [guest_allow] => 2
        )

    [1] => Array
        (
            [property_id] => 9
            [guest_allow] => 3
        )

    [2] => Array
        (
            [property_id] => 62
            [guest_allow] => 2
        )

    [3] => Array
        (
            [property_id] => 72
            [guest_allow] => 3
        )

    [4] => Array
        (
            [property_id] => 76
            [guest_allow] => 4
        )

    [5] => Array
        (
            [property_id] => 80
            [guest_allow] => 5
        )

    [6] => Array
        (
            [property_id] => 84
            [guest_allow] => 3
        )
)

所以我必须匹配guest数组，所有值都存在于第二个数组中，并且我必须检查guest虚拟机值小于guest_allow的第二个数组。如果没有匹配单值返回空数组。如果匹配值，则返回仅匹配值。我想要这样的返回数组：

       Array
(
    [0] => Array
        (
            [property_id] => 6
            [guest_allow] => 2
        )

    [1] => Array
        (
            [property_id] => 9
            [guest_allow] => 3
        )

    [2] => Array
        (
            [property_id] => 62
            [guest_allow] => 2
        )

    [3] => Array
        (
            [property_id] => 72
            [guest_allow] => 3
        )

    [4] => Array
        (
            [property_id] => 84
            [guest_allow] => 3
        )
    [5] => Array
        (
            [property_id] => 76
            [guest_allow] => 4
        )
)

是否可以返回此类型数组？感谢。

Answer 1

假设$guestArr是您的来宾数组而$secondArr是您的第二个数组，解决方案将是这样的：

foreach($secondArr as $key => $arr){
    if(!in_array($arr['guest_allow'], $guestArr)){
        unset($secondArr[$key]);
    }
}

// display $secondArr array
var_dump($secondArr);

这里是live demo。

Answer 2

$first = [1, 2, 3];
$second = [
    ['property_id' => 6, 'guest_allow' => 2],
    ['property_id' => 66, 'guest_allow' => 3],
    ['property_id' => 76, 'guest_allow' => 4],
    ['property_id' => 86, 'guest_allow' => 2]
];

$result = array_filter($second, function($el) use ($first) {
    return in_array($el['guest_allow'], $first);
});

PHP比较两个多维数组
