使用php从多维数组中获得所有可能的组合(或排列)

function getArrayCombinations($array) {
    $result = [[]];
    foreach ($array as $values) {
        $temp = [];
        foreach ($result as $combination) {
            foreach ($values as $value) {
                $temp[] = array_merge($combination, [$value]);
            }
        }
        $result = $temp;
    }
    return $result;
}

// 示例用法
$array = [
    ['A', 'B'],
    ['1', '2', '3'],
    ['X', 'Y']
];

$combinations = getArrayCombinations($array);
print_r($combinations);
