如何從對象數組中過濾掉一個對象？

我有一個如下的對象數組;我如何過濾（刪除）具有admins-> member = 11的對象？如何從對象數組中過濾掉一個對象？

在這個例子中，結果數組對象只有第一個對象[245]在開始。

$arr = array_filter($arr, function($item) 
{ 
    if(!isset($item->admins) || !is_array($item->admins)) 
    { 
     return false; 
    } 
    foreach($item->admins as $admin) 
    { 
     if($admin->member == 11) 
     { 
      return true; 
     } 
    } 
    return false; 
});

（PHP 5.3中使用匿名函數）

可能還想使用if（property_exists（$ item，'admins'））來確保對象實際上有一個管理變量。這個問題並不清楚他的對象是否是同質的 – carpii

嗨carpii，是的的確我們應該檢查對象是否是同質的第一... 蒂姆，我怎麼能過濾使用for循環的上述數組？因爲它看起來像明確使用索引0的答案，因爲在我的例子中，這是出現$ item-> admins [0] - > member == 11的地方，但是如果我不知道哪個對象有什麼？謝謝！ – Alex

@Alex：查看我剛纔編輯的內容是否解決了您提到的問題。 –
