Question

我不是PHP开发者。我正在使用谷歌API，我使用的后端是PHP。我正在处理一个示例，该示例返回给定邮政编码的特定距离内的位置。从PHP返回的结果集格式如下..

    Array
(
[0] => Array
(
[id] => 554
[postcode] => 1225
[suburb] => Royal Exchange
[aus_post_name] => ROYAL EXCHANGE
[state] => NSW
[lat] => -33.864393
[lon] => 151.209608
)

[1] => Array
(
[id] => 559
[postcode] => 1230
[suburb] => Queen Victoria Building
[aus_post_name] => QUEEN VICTORIA BUILDING
[state] => NSW
[lat] => -33.872049
[lon] => 151.206428
)

[2] => Array
(
[id] => 714
[postcode] => 2000
[suburb] => Barangaroo
[aus_post_name] => BARANGAROO
[state] => NSW
[lat] => -33.858315
[lon] => 151.203519
)

[3] => Array
(
[id] => 715
[postcode] => 2000
[suburb] => Dawes Point
[aus_post_name] => DAWES POINT
[state] => NSW
[lat] => -33.855601
[lon] => 151.20822
)

如何循环结果集，并获取值，例如状态和郊区？

Answer 1

使用for loop或foreach loop：

foreach ($bigarray as $row) {
    echo $row['suburb'];  // suburb
    echo $row['state'];   // state
}

Answer 2

用于循环。这是获取州和郊区数据的最佳方式..以下代码将帮助您..

$arr_var=Array
(
     0 => Array
     (
       'id' => 554,
       'postcode' => 1225,
       'suburb' => 'Royal Exchange',
       'aus_post_name' =>'ROYAL EXCHANGE',
       'state' => 'NSW',
       'lat' => -33.864393,
       'lon' => 151.209608
    ),

1 => Array
   (
       'id' => 559,
       'postcode' => 1230,
       'suburb' => 'Queen Victoria Building',
       'aus_post_name' => 'QUEEN VICTORIA BUILDING',
       'state' => 'NSW',
       'lat' => -33.872049,
      'lon' => 151.206428,
   )
);

for($i=0;count($arr_var)>$i;$i++)
{
    echo " state : ".$arr_var[$i]['state'];
    echo " suburb : ".$arr_var[$i]['suburb'];
}

循环PHP数组
