多维数组无法打印值

Question

I have a multidimensional array coming from JSON. I cannot seem to get to print one value from all. It either gives me nothing or says array. I need to print all the zip_code fields.

 $spit = json_decode($result);

Yields:

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
            )

I have tried to access with $zip=$spit->zip_codes->zip_code; and $zip=['zip_codes']['zip_code'];

I am sure I am just missing the obvious but have tried about 20 ways to echo it out with no luck.

Change

$spit = json_decode($result);

to

$spit = json_decode($result,1);

This will convert JSON into an array and then you can print the zip code as

print_r($spit["zip_codes"]);
