Amazon PHP SDK列出对象

Question

我的代码很简单

 $objects = $s3->list_objects("mybucket",array("max-keys"=>5));
 var_dump($objects);

Object(CFResponse)[107]
    public 'header' => 
    array (size=11)
      'x-amz-id-2' => string      
    ...
    public 'body' => 
    object(CFSimpleXML)[106]
      public '@attributes' => 
        array (size=1)
          'ns' => string 'http://s3.amazonaws.com/doc/2006-03-01/' (length=39)
      public 'Name' => string 'cdneu.2yourfacecdn.com' (length=22)
      public 'Prefix' => 
        object(CFSimpleXML)[3]
      public 'Marker' => 
        object(CFSimpleXML)[105]
      public 'MaxKeys' => string '5' (length=1)
      public 'IsTruncated' => string 'true' (length=4)
      public 'Contents' => 
        array (size=5)
          0 => 
            object(CFSimpleXML)[104]
              ...
          1 => 
            object(CFSimpleXML)[103]
              ...
          2 => 
            object(CFSimpleXML)[102]
              ...
          3 => 
            object(CFSimpleXML)[101]
              ...
          4 => 
            object(CFSimpleXML)[100]
              ...
         public 'status' => int 200

我相信“内容”下面的部分就是我要找的，但是我该如何访问它呢？我习惯于接收数组，在那里我可以弄清楚键是什么以及如何访问，但这对我来说很难，有没有人猜到？

Answer 1

尝试此操作，以列出每个对象的关键元素：

$s3 = new AmazonS3();
$objects = $s3->list_objects("YOUR BUCKET NAME",array("max-keys"=>5));
foreach ($objects->body->Contents as $item){
    print_r($item->Key."");
}

Answer 2

您可以按如下方式访问内容

$contents = $objects['Contents'];
