ここにphpコードがあります

<?php
require("dbinfo.php");

// Start XML file, create parent node
$doc = domxml_new_doc("1.0");
$node = $doc->create_element("markers");
$parnode = $doc->append_child($node);

// Opens a connection to a MySQL server
$connection=mysql_connect ('localhost', $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());
}

// Select all the rows in the markers table
$query = "SELECT * FROM markers WHERE 1";
$result = mysql_query($query);
if (!$result) {
  die('Invalid query: ' . mysql_error());
}

header("Content-type: text/xml");

// 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("name", $row['name']);
  $newnode->set_attribute("address", $row['address']);
  $newnode->set_attribute("lat", $row['lat']);
  $newnode->set_attribute("lng", $row['lng']);
  $newnode->set_attribute("type", $row['type']);
}

$xmlfile = $doc->dump_mem();
echo $xmlfile;

https://developers.google.com/maps/articles/phpsqlajax_v3に従っているだけで、コードの何が問題なのかわかりません。データベース、xml をチェックしました。すべてが機能しています..どんな助けでも大歓迎です。どうもありがとうございます。

それを試してみてください：

 var icon = customIcons['simple'] || {};
          var marker = new google.maps.Marker({
            map: map,
            position: point,
            icon: icon.icon,
            shadow: icon.shadow
          });

この行に不正な空白があります:

<script type="text/javascript" src="http://maps.googleapis.com/maps/api    /js?sensor=false"></script>

に変更します。

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>

実際の例(データ用にこれのローカル コピーを使用)
