您好，对这个问题的任何建议将不胜感激，因为它似乎应该是一个简单的问题，但它给我带来了很大的困难。
我一直在遵循位于https://developers.google.com/maps/articles/phpsqlajax的教程“使用 PHP/MySQL 和 Google 地图”来生成 kml/xml 文件。我生成的 kml 文件与示例中看到的文件不同，因为我正在生成一系列建筑物的多边形边界，而不仅仅是在特定位置创建地点标记。此页面的代码如下所示...
// Creates the Document.
$dom = new DOMDocument('1.0', 'UTF-8');
// Creates the root KML element and appends it to the root document.
$node = $dom->createElementNS('http://earth.google.com/kml/2.1', 'kml');
$parNode = $dom->appendChild($node);
// Creates a KML Document element and append it to the KML element.
$dnode = $dom->createElement('Document');
$docNode = $parNode->appendChild($dnode);
//Style 1
//Set Style ID
$restStyleNode = $dom->createElement('Style');
$restStyleNode->setAttribute('id', '#style1');
$restIconstyleNode = $dom->createElement('IconStyle');
$restIconstyleNode->setAttribute('id', 'BuildingIcon');
//Set LineStyle
$restIconNode = $dom->createElement('LineStyle');
$restHref = $dom->createElement('colour', 'FF990000');
$restIconNode->appendChild($restHref);
$restWidth = $dom->createElement('width', '2');
$restIconNode->appendChild($restWidth);
$restIconstyleNode->appendChild($restIconNode);
$restStyleNode->appendChild($restIconstyleNode);
$docNode->appendChild($restStyleNode);
//Set Polystyle
$restIconNode = $dom->createElement('PolyStyle');
$restHref = $dom->createElement('colour', 'FFCC0000');
$restIconNode->appendChild($restHref);
$restFill = $dom->createElement('fill', '1');
$restIconNode->appendChild($restFill);
$restOutline = $dom->createElement('outline', '1');
$restIconNode->appendChild($restOutline);
$restIconstyleNode->appendChild($restIconNode);
$restStyleNode->appendChild($restIconstyleNode);
$docNode->appendChild($restStyleNode);
//Style 2
//Set Style ID
$restStyleNode = $dom->createElement('Style');
$restStyleNode->setAttribute('id', '#style2');
$restIconstyleNode = $dom->createElement('IconStyle');
$restIconstyleNode->setAttribute('id', 'HighfieldIcon');
//Set LineStyle
$restIconNode = $dom->createElement('LineStyle');
$restHref = $dom->createElement('colour', 'ff000000');
$restIconNode->appendChild($restHref);
$restWidth = $dom->createElement('width', '2');
$restIconNode->appendChild($restWidth);
$restIconstyleNode->appendChild($restIconNode);
$restStyleNode->appendChild($restIconstyleNode);
$docNode->appendChild($restStyleNode);
//Set Polystyle
$restIconNode = $dom->createElement('PolyStyle');
$restHref = $dom->createElement('colour', 'ff000000');
$restIconNode->appendChild($restHref);
$restFill = $dom->createElement('fill', '1');
$restIconNode->appendChild($restFill);
$restOutline = $dom->createElement('outline', '1');
$restIconNode->appendChild($restOutline);
$restIconstyleNode->appendChild($restIconNode);
$restStyleNode->appendChild($restIconstyleNode);
$docNode->appendChild($restStyleNode);
// Iterates through the MySQL results, creating one Placemark for each row.
while ($row = @mysql_fetch_assoc($result))
{
// Creates a Placemark and append it to the Document.
$node = $dom->createElement('Placemark');
$placeNode = $docNode->appendChild($node);
// Creates an id attribute and assign it the value of id column.
$placeNode->setAttribute('id', 'placemark' . $row['buildingID']);
// Create name, and description elements and assigns them the values of the name and address columns from the results.
$nameNode = $dom->createElement('name',htmlentities($row['name']));
$placeNode->appendChild($nameNode);
$styleUrl = $dom->createElement('styleUrl', $row['styleID']);
$placeNode->appendChild($styleUrl);
// Creates a Polygon element.
$polygonNode = $dom->createElement('Polygon');
$placeNode->appendChild($polygonNode);
//Add extrude information
$restExtrude = $dom->createElement('extrude', '1');
$polygonNode->appendChild($restExtrude);
//Add altitude information
$restAltitude = $dom->createElement('altitudeMode', 'relativeToGround');
$polygonNode->appendChild($restAltitude);
//Add outerBoundaryIsNode
$outerBoundaryIsNode = $dom->createElement('outerBoundaryIs');
$polygonNode->appendChild($outerBoundaryIsNode);
//Add LinearRing Node
$LinearRingNode = $dom->createElement('LinearRing');
$outerBoundaryIsNode->appendChild($LinearRingNode);
//Adding information into linear ring node
$tessellate = $dom->createElement('tessellate', '1');
$LinearRingNode->appendChild($tessellate);
// Creates a coordinates element and gives it the value of the lng and lat columns from the results.
$coorStr = $row['longitude1'] . ',' . $row['latitude1'] . ' ' . $row['longitude2'] . ',' . $row['latitude2'] . ' ' . $row['longitude3'] . ',' . $row['latitude3'] . ' ' . $row['longitude4'] . ',' . $row['latitude4'] . ' ' . $row['longitude5'] . ',' . $row['latitude5'];
$coorNode = $dom->createElement('coordinates', $coorStr);
$LinearRingNode->appendChild($coorNode);
}
$kmlOutput = $dom->saveXML();
header('Content-type: application/vnd.google-earth.kml+xml');
echo $kmlOutput;
我已经检查了通过将其加载到地图中生成的 kml 文件，我对结果感到满意，但是我无法终生弄清楚如何让我的网站显示我的 php 文件正在生成的任何 kml 文件。我只是想不出该怎么做。我已经尝试按照教程的建议进行操作，但是我真的不明白它在做什么，我无法让它工作。开发 php 代码来动态生成 kml 文件后，我认为我已经完成了困难的部分，我觉得我错了。任何建议将不胜感激，因为它非常重要！
目前我正在使用以下代码：
<script src="http://maps.google.com/maps?file=api&v=2&key=key
" type="文本/javascript">
var map;
var geoXml;
var toggleState = 1;
function initialize()
{
if (GBrowserIsCompatible())
{
geoXml = new GGeoXml("Locationoffile.part");
map = new GMap2(document.getElementById("map_canvas"));
map.setCenter(new GLatLng(50.xxxxx,-1.xxxxxxx), 16);
map.addControl(new GLargeMapControl());
map.addOverlay(geoXml);
}
}
function toggleMyKml()
{
if (toggleState == 1)
{
map.removeOverlay(geoXml);
toggleState = 0;
}
else
{
map.addOverlay(geoXml);
toggleState = 1;
}
}
通过将 php 生成的 kml 文件的输出复制到静态位置来生成地图。这行得通。我需要编辑多少才能让它加载我的 php 文件？尽管有你的帮助，我还是有点困惑。
