在php循环之外设置文本

我被一件可能很简单的事情困住了…就是想不出来。我有这个：

echo“待定的朋友是-”$等待你的朋友。“
”在我的循环中。在输出时，我需要
$pending\u friend\u 1
在循环中，否则我无法获得完整的结果循环。如何取出文本
待处理的朋友是-
，使其仍然与列表拼凑在一起。我正在尝试这样做：

待定的朋友是-

您可以尝试以下方法：

    AND status = ?
";
$pending_friend_count_stmt = $con->prepare($friends_pending_sql);
$pending_friend_count_stmt->execute(array($user_id, $status_one));
$pending_friend_rows = $pending_friend_count_stmt->fetchAll(PDO::FETCH_ASSOC);
echo '<div id="pending-request_count">Total Pending Friends -' . $total_pending_count . '</div>';
foreach ($pending_friend_rows as $pending_friend_row) {
    $pending_friend_1           = $pending_friend_row['friend_one'];
