如何将二维数组内爆为array_intersect的参数

<?php
function flattenArray($array) {
    $result = [];
    foreach ($array as $value) {
        if (is_array($value)) {
            $result = array_merge($result, flattenArray($value));
        } else {
            $result[] = $value;
        }
    }
    return $result;
}

$array1 = [[1, 2], [3, 4]];
$array2 = [[2, 3], [4, 5]];

$flattenedArray1 = flattenArray($array1);
$flattenedArray2 = flattenArray($array2);

$intersection = array_intersect($flattenedArray1, $flattenedArray2);

print_r($intersection); // 输出: Array ( [1] => 2 [2] => 3 [3] => 4 )
?>
