【问题描述】：
由于我无法与 Google Maps Api 中的商店查找器相处（请参阅我的其他未答复的问题），因此我尝试以另一种方式应对它：通过 php-mysql-query 和 xml-file 将所有位置放入一张地图并通过文本输入搜索我自己的位置。 每项工作单独工作都很好，但是在组合时，我没有得到我所在位置的标记，即地理编码器似乎无法正常工作。但是：当我输入一个废话地址时，我得到一个正确的错误信息。所以在我看来，地理编码的标记无法显示，但我不知道为什么。有人可以帮忙吗？这是示例（http://umwelt-und-information.com/maps/ASPE_Adressen_zeigen.php），这里是代码：
<?php
//error_reporting(E_ALL);
require("dbpass.php");
if (PHP_VERSION>='5')
require_once('domxml-php4-to-php5.php');
// Opens a connection to a mySQL server
$connection=mysql_connect ($dbhost, $username, $password);
if (!$connection) {
die('Not connected : ' . mysql_error());
}
// Set the active mySQL database
$db_selected = mysql_select_db($database, $connection);
if (!$db_selected) {
die ('Can\'t use db : ' . mysql_error());
}
// Start XML file, create parent node
$doc = domxml_new_doc("1.0");
$node = $doc->create_element("markers");
$parnode = $doc->append_child($node);
// Select all the rows in the ASPE table
$query = "SELECT DISTINCT Nachname, lng, lat, Strasse, Telefon_P, Telefon_D, Telefon_M FROM ASPE";
$result = mysql_query($query) or die ("Error in query: $query " . mysql_error());
// Iterate through the rows, adding XML nodes for each
while ($row = @mysql_fetch_assoc($result)){
// ADD TO XML DOCUMENT NODE
$node = $doc->create_element("marker");
$newnode = $parnode->append_child($node);
$newnode->set_attribute("Nachname", $row['Nachname']);
$newnode->set_attribute("Strasse ", $row['Strasse']);
$newnode->set_attribute("Telefon_P", $row['Telefon_P']);
$newnode->set_attribute("Telefon_D", $row['Telefon_D']);
$newnode->set_attribute("Telefon_M", $row['Telefon_M']);
$newnode->set_attribute("lat", $row['lat']);
$newnode->set_attribute("lng", $row['lng']);
}
$xmlfile = $doc->dump_file("ASPE.xml");
mysql_close($connection);
