PHP得到JSON

Question

數組值使用PHP，我怎麼會訪問內部數組值，具體到這個例子具體到每場比賽的數組中的值，從JSON供稿與此類似：

Array 
(
[startIndex] => 3 
[refreshInterval] => 60 
[games] => Array 
    (
     [0] => Array 
      (
       [id] => 2013020004 
       [gs] => 5 
       [ts] => WEDNESDAY 10/2 
       [tsc] => final 
       [bs] => FINAL 
       [bsc] => final 
      ) 

     [1] => Array 
      (
       [id] => 2013020005 
       [gs] => 5 
       [ts] => WEDNESDAY 10/2 
       [tsc] => final 
       [bs] => FINAL 
       [bsc] => 
      ) 

我有嘗試在類似foreach循環中嵌套一個foreach循環：

foreach ($json as $key => $jsons) { 
foreach ($jsons as $my => $value) { 
    echo $value; 
} 
} 

Answer 1

如果這是你正在尋找一個數組，那麼你可以達到的數值

foreach($json["games"] as $game) { 
    foreach ($game as $key => $value) { 
     echo $value; 
    } 
} 

這應該給你在遊戲的每個部分陣列內的值。

編輯：回答獲得遊戲像id的具體數值，將不再需要

第二foreach循環在評論額外問題。相反，做到以下幾點：

foreach($json["games"] as $game) { 
    echo $game['id']; 
} 

Answer 2

您只需將其作爲關聯數組訪問即可。

$json['games'][0]['id'] // This is 2013020004 
$json['games'][1]['id'] // This is 2013020005 

您可以通過像這樣的遊戲循環：

foreach($json['games'] as $game){ 
    print_r($game); 
} 

Answer 3

如果您嘗試訪問此，

[0] => Array 
     (
      [id] => 2013020004 
      [gs] => 5 
      [ts] => WEDNESDAY 10/2 
      [tsc] => final 
      [bs] => FINAL 
      [bsc] => final 
     ) 

    [1] => Array 
     (
      [id] => 2013020005 
      [gs] => 5 
      [ts] => WEDNESDAY 10/2 
      [tsc] => final 
      [bs] => FINAL 
      [bsc] => 
     ) 

..then你是對的這樣做。唯一的問題是你試圖回顯一個數組。嘗試使用print_r($value)。如果你想要一個特定的值，比如id。您可以echo $value['id'];

Answer 4

我想你可以使用遞歸array_key_search的many example之一。這樣你可以簡單地做到：

$firstGame = array_search_key(0, $array); 
$firstGameId = $firstGame["id"];
