php - 另一个php数组循环问题

Question

似乎一直在与这个战斗，就像永远一样。

我有一个数组:

$url_array

它包含以下信息:

Array ( 
   [ppp] => Array ( 
      [0] => stdClass Object ( 
         [id] => 46660 
         [entity_id] => 0 
         [redirect_url] => http://www.google.com 
         [type] => Image 
      ) 
      [1] => stdClass Object ( 
         [id] => 52662 
         [entity_id] => 0 
         [pixel_redirect_url] => http://www.yahoo.com 
         [type] => Image 
      ) 
      [2] => stdClass Object ( 
         [id] => 53877 
         [entity_id] => 0 
         [redirect_url] => http://www.msn.com 
         [pixel_type] => Image 
      ) 
   ) 
   [total_count] => 3 
)

我需要遍历它，并对每个变量做一些事情。我可以让它工作:

foreach ($piggies_array as $key => $value) {
$id = $value[0]->id;
$redirect_url = $value[0]->redirect_url; }

不出所料，它只是回显了这些变量的第一个值，但无论我尝试什么，我都无法让它循环:

$value->redirect_url;
$value=>redirect_url;

如有任何帮助，我将不胜感激。

这应该可以解决问题:

foreach ($url_array['ppp'] as $key => $object) {
    echo $object->redirect_url;
}
