首先把线去掉echo "<br>";从getLatestMessage函数中 - 这会添加一个您不想要的新行。其次，将该函数中的所有 echo 转换为字符串连接，然后从函数返回字符串 - 这使您可以更好地控制在何处使用它生成的结果。第三，尝试在user_found_messagesdiv 内回显消息数据 - 因为 div 是块级元素，通常也会开始一个新行（除非 CSS 规则告诉它们不要这样做）。所以，我想是这样的：public function getLatestMessage ($userLoggedIn, $user2) {&nbsp; &nbsp; $query = $this->con->prepare('SELECT body, user_to, date FROM messages WHERE&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; user_to = ? AND user_from = ? OR user_to = ? AND user_from = ? ORDER BY id DESC LIMIT 1');&nbsp; &nbsp; $query->bind_param("ssss", $userLoggedIn, $user2, $user2, $userLoggedIn);&nbsp; &nbsp; $query->execute();&nbsp; &nbsp; //$query->bind_result($body, $user_to, $date);&nbsp; &nbsp; $query_result = $query->get_result();&nbsp; &nbsp; $msg = ""; //to hold the message data&nbsp; &nbsp; &nbsp;if ($row = $query_result->fetch_assoc()) { //don't need a while here because we've limited the query to one record&nbsp; &nbsp; &nbsp; &nbsp; //Timeframe&nbsp; &nbsp; &nbsp; &nbsp; $date_time_now = date("Y-m-d H:i:s");&nbsp; &nbsp; &nbsp; &nbsp; $start_date = new DateTime($row['date']); //Time of post&nbsp; &nbsp; &nbsp; &nbsp; $end_date = new DateTime($date_time_now); //Current time&nbsp; &nbsp; &nbsp; &nbsp; $interval = $start_date->diff($end_date); //Difference between dates&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; if($interval->y >= 1) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if($interval->y == 1)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $time_message = $interval->y .
