我有一个PHP多维数组，我只想循环通过一个数组，例如数组"a"或数组"b"，有什么建议吗？

Array
(
    [59] => Array
        (
            ["a"] => Array
                (
                    [0] => stdClass Object
                        (
                            [id] => 59
                            [user_id] => 122
                            [city_id] => 1
                            [country] => 2
                        )
                    [1] => stdClass Object
                        (
                            [id] => 59
                            [user_id] => 123
                            [city_id] => 11
                            [country] => 3
                        )
                )
            ["b"] => Array
                (
                    [0] => stdClass Object
                        (
                            [id] => 59
                            [user_id] => 124
                            [city_id] => 23
                            [country] => 1
                        )
                )
        )
)

谢谢！

您需要访问正确的索引，然后：

foreach($myArray[59]['a'] as $value){
}

或

for($i = 0; $i < count($myArray[59]['a']); $i++){
// do something with $myArray[59]['a'][$i];
}
