Question

我有一个来自JSON的多维数组。我似乎无法从所有人打印一个值。它要么没有给我任何东西，要么说array。我需要打印所有zip_code字段。

 $spit = json_decode($result);

收率：

stdClass Object
   (
  [zip_codes] => Array
    (
        [0] => stdClass Object
            (
                [zip_code] => 33779
                [distance] => 9.513
                [city] => Largo
                [state] => FL
            )

        [1] => stdClass Object
            (
                [zip_code] => 33771
                [distance] => 9.188
                [city] => Largo
                [state] => FL
            )

        [2] => stdClass Object
            (
                [zip_code] => 33760
                [distance] => 9.989
                [city] => Clearwater
                [state] => FL
            )

        [3] => stdClass Object
            (
                [zip_code] => 33770
                [distance] => 8.525
                [city] => Largo
                [state] => FL
            )

        [4] => stdClass Object
            (
                [zip_code] => 33786
                [distance] => 8.153
                [city] => Belleair Beach
                [state] => FL
            )

        [5] => stdClass Object
            (
                [zip_code] => 33764
                [distance] => 7.651
                [city] => Clearwater
                [state] => FL
            )

        [6] => stdClass Object
            (
                [zip_code] => 33756
                [distance] => 6.373
                [city] => Clearwater
                [state] => FL
            )

我尝试使用$zip=$spit->zip_codes->zip_code;和$zip=['zip_codes']['zip_code'];

进行访问

我确信我只是错过了显而易见的事情，但已经尝试了大约20种方法来回应它而没有运气。

更改

$spit = json_decode($result);

到

$spit = json_decode($result,1);

这会将JSON转换为数组，然后您可以将邮政编码打印为

print_r($spit["zip_codes"]);

多维数组不能打印值
