在PHP中删除多维数组中的重复数组

function removeDuplicateArrays($array) {
    $stringifiedArray = array_map('json_encode', $array);
    $uniqueArray = array_unique($stringifiedArray);
    $resultArray = array_map('json_decode', $uniqueArray);
    return $resultArray;
}

// 示例用法
$multiDimensionalArray = [
    ['name' => 'John', 'age' => 25],
    ['name' => 'Jane', 'age' => 30],
    ['name' => 'John', 'age' => 25],
    ['name' => 'Jane', 'age' => 30]
];

$filteredArray = removeDuplicateArrays($multiDimensionalArray);
print_r($filteredArray);

Array
(
    [0] => Array
        (
            [name] => John
            [age] => 25
        )

    [1] => Array
        (
            [name] => Jane
            [age] => 30
        )

)
