wordpress unset user_meta數組值

Question

我嘗試了常規的PHP未設置，但沒有成功。一切看起來都在這裏，但它仍然在陣列中

$profileID = $_POST['profileID']; 
$userID = $_POST['userID']; 

    $reChkMetaValue = get_user_meta($userID,'friends',true); 
    foreach($reChkMetaValue as $key => $value) { 

if(($key = array_search($profileID, $reChkMetaValue)) !== false); 
    unset($reChkMetaValue[$key]); 
    }

嘗試做一個對用戶meta的foreach。如果數據的值匹配，請記錄密鑰。然後從數組中取消設置。

<?php 
    $user_meta = get_user_meta($userID,'favs',true); 
    $key_found = false; 
    foreach($user_meta as $key => $value) 
    { 
     if(!$key_found){ 
      if($value == 'THE THING YOU WANT TO FIND'){ 
       $remove_key = $key; 
       $key_found = true; 
      } 
     } 
    } 
    unset($user_meta[$remove_key]); 
?>
