如何从内部键和值与第一个数组匹配的第二个数组中找到数组键?

How can I find the array key from second array where the inner keys and values match first array?

我有数组 #1,其中包含:

Array
(
    [attribute_pa_color] => blue
    [attribute_pa_size] => large
)

我有数组 #2,其中包含:

Array
(
    [4624] => Array
        (
            [attribute_pa_color] => blue
            [attribute_pa_size] => large
        )

    [4625] => Array
        (
            [attribute_pa_color] => blue
            [attribute_pa_size] => medium
        )

    [4626] => Array
        (
            [attribute_pa_color] => blue
            [attribute_pa_size] => small
        )

)

如何从数组 #2 中找到数组键,其中内部键和值与数组 1 匹配?

我一直在尝试使用多个 foreach,但我似乎无法做到这一点,这是我目前的想法:

$i = 0;
foreach( $array_2 as $array2_key => $array2_array ) {

    foreach( $array2_array as $a2_key => $a2_value ) {

        if( $a2_value == $array1[$a2key] ) {

            $i = $i + 1;

            if( $i == count( $array1 ) ) {

                $break = 1;

            }

            if( $break == 1 ) {

                break;

            }

        }

    }

    if( $break == 1 ) {

        echo 'key is: ' . $array2_key;

        break;

    }

}

数组可以比较==:

foreach ($array2 as $key => $item) {
    if ($item == $array1) {
        echo 'Item with key ' . $key;
    }
}

因为 array_search 接受针数组,所以更容易:

$key = array_search($array1, $array2);
