我的谷歌地图中我的标记信息窗口有问题。标记显示正确，但每当您单击标记时，它只会显示最后一个标记集的信息（在最后一个标记上方）。这是我的代码：
<?php
//Open connection to database to fetch markers from maps table:
require_once("config.php"); // get config
$con = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD); // connect to db
if (!$con) die('Could not connect: ' . mysql_error());
mysql_select_db("drpayne_test", $con); // select db
$q = "SELECT * FROM maps"; // form query
$result = mysql_query($q); // run query
// output the start of the HTML Map Page
echo <<<END
