Google Map API PHP示例

我使用的創建商店定位器提供了https://developers.google.com/maps/articles/phpsqlsearch_v3提供的PHP，MySQL和Google Maps示例。Google Map API PHP示例

我遇到了XML文檔寫入的問題。我可以從Querious（數據庫應用程序）運行查詢成功，但是當試圖運行提供的腳本（我將其修改爲mysqli）時，事情並不適合我。我沒有得到任何回報。數據庫的設置與示例中提供的一樣。下面是修改的PHP，我使用：

PHP

<?php 
require_once('../includes/connection.php'); 
require_once('../includes/function.php'); 

// Get parameters from URL 
$center_lat = $_GET["lat"]; 
$center_lng = $_GET["lng"]; 
$radius = $_GET["radius"]; 

// Start XML file, create parent node 
$dom = new DOMDocument("1.0"); 
$node = $dom->createElement("markers"); 
$parnode = $dom->appendChild($node); 

// Search the rows in the markers table 
$query = sprintf("SELECT address, name, lat, lng, (3959 * acos(cos(radians('%s')) * cos(radians(lat)) * cos(radians(lng) - radians('%s')) + sin(radians('%s')) * sin(radians(lat)))) AS distance FROM markers HAVING distance < '%s' ORDER BY distance LIMIT 0 , 20", 
    mysqli_real_escape_string($mysqli , $center_lat), 
    mysqli_real_escape_string($mysqli , $center_lng), 
    mysqli_real_escape_string($mysqli , $center_lat), 
    mysqli_real_escape_string($mysqli , $radius)); 
$result = mysqli_query($mysqli, $query); 
$result = mysqli_query($mysqli, $query); 
if (!$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)){ 
    $node = $dom->createElement("marker"); 
    $newnode = $parnode->appendChild($node); 
    $newnode->setAttribute("name", $row['name']); 
    $newnode->setAttribute("address", $row['address']); 
    $newnode->setAttribute("lat", $row['lat']); 
    $newnode->setAttribute("lng", $row['lng']); 
    $newnode->setAttribute("distance", $row['distance']); 
} 
echo $dom->saveXML() 
?>

我知道，無論我的連接是成功的，其功能是免費的錯誤。感謝您對此的任何見解。
