解析在PHP

Question

解碼JSON數組我有我從Facebook的API接收的解碼JSON數組：

$Myposts = json_decode($response->getBody()); 

當我印刷$ Myposts：

var_dump($Myposts); 

它紅粉此：

object(stdClass)[16] 
    public 'data' => 
    array (size=24) 
     0 => 
     object(stdClass)[12] 
      public 'message' => string 'a mesagge..' (length=65) 
      public 'created_time' => string '2016-09-18T16:41:10+0000' (length=24) 
      public 'id' => string '111110037' (length=35) 
     1 => 
     object(stdClass)[28] 
      public 'message' => string 'How brave !' (length=11) 
      public 'story' => string 'XXX shared Le XX video.' (length=59) 
      public 'created_time' => string '2016-09-18T13:37:33+0000' (length=24) 
      public 'id' => string '102172976' (length=35) 

     23 => 
     object(stdClass)[50] 
      public 'message' => string '...a message..' (length=259) 
      public 'story' => string 'Bi added 3 new photos.' (length=33) 
      public 'created_time' => string '2015-12-11T20:54:21+0000' (length=24) 
      public 'id' => string '102191588' (length=35) 
    public 'paging' => 
    object(stdClass)[51] 
     public 'previous' => string 'https://graph.facebook.com/v2.7/XXXX&__paging_token=YYYY&__previous=1' (length=372) 
     public 'next' => string 'https://graph.facebook.com/v2.7/XXX/feed?access_token=DDDD&limit=25&until=XXX&__paging_token=XXXX' (length=362) 

我是新來的PHP，我不知道如何處理這個輸出，我想遍歷所有的消息，並輸出cre每條消息的ated_time。

任何想法？

編輯：我試過：echo $myPosts['data'][message];從Parsing JSON file with PHP，但我有：「未定義的指數：消息」。這就是爲什麼我發佈了一個新問題。

的json_decode第二個參數接通結果到關聯數組：

$myPosts = json_decode($response->getBody(), true); 

foreach ($myPosts['data'] as $post) { 
    var_dump($post['message']); 
} 

在不使用第二個參數的解碼返回對象：HTTP：//計算器

$myPosts = json_decode($response->getBody()); 

foreach ($myPosts->data as $post) { 
    var_dump($post->message); 
}
