我在我的谷歌地圖中我的標記信息窗口出現問題。標記正確顯示，但每當你點擊一個標記時，它只顯示最後一個標記集的信息（在最後一個標記之上）。這裏是我的代碼：谷歌地圖信息標記只顯示最後一個標記
<?php
//Open connection to database to fetch markers from maps table:
require_once("config.php"); // get config
$con = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD); // connect to db

mysql_select_db("drpayne_test", $con); // select db
$q = "SELECT * FROM maps"; // form query
