如何使站点地图中的根索引优先级为 1.0,其余子目录文件的优先级为 0.5?
我正在使用这个 php 代码在访问页面时动态生成我的站点地图。
就像现在一样,它优先考虑设置值是什么
$url -> appendChild( $priority = $xml->createElement('priority', '0.5') );
对于站点地图中的每个 url,如下例所示:
创建站点地图的 PHP 代码:
<?
$ignore = array( 'images', 'css', 'includes', 'cgi-bin', 'xml-sitemap.php' );
function getFileList($dir, $recurse=false) {
global $ignore;
$retval = array();
// open pointer to directory and read list of files
$d = @dir($dir) or die("getFileList: Failed opening directory $dir for reading");
while ( false !== ( $entry = $d->read() ) ) {
// Check if this dir needs to be ignored, if so, skip it.
if ( in_array( utf8_encode( $entry ), $ignore ) )
continue;
// skip hidden files
if($entry[0] == ".") continue;
if(is_dir("$dir$entry")) {
$retval[] = array(
"name" => "$dir$entry/",
"type" => filetype("$dir$entry"),
"size" => 0,
"lastmod" => filemtime("$dir$entry")
);
if($recurse && is_readable("$dir$entry/")) {
$retval = array_merge($retval, getFileList("$dir$entry/", true));
}
} elseif(is_readable("$dir$entry")) {
$retval[] = array(
"name" => str_replace('./','/', $dir),
"type" => mime_content_type("$dir$entry"),
"size" => filesize("$dir$entry"),
"lastmod" => filemtime("$dir$entry")
);
}
}
$d->close();
return $retval;
}
$dirlist = getFileList("./", true);
// sitemap creation
$time = time();
$sitemap = $_SERVER['DOCUMENT_ROOT'].'/sitemap.xml';
if ($time - filemtime($sitemap) >= 1) { // 1 days
$xml = new DomDocument('1.0', 'utf-8');
$xml->formatOutput = true;
// creating base node
$urlset = $xml->createElement('urlset');
$urlset -> appendChild(
new DomAttr('xmlns', 'http://www.sitemaps.org/schemas/sitemap/0.9')
);
// appending it to document
$xml -> appendChild($urlset);
// building the xml document with your website content
foreach($dirlist as $file)
{
if($file['type'] != 'text/x-php') continue;
//Creating single url node
$url = $xml->createElement('url');
//Filling node with entry info
$url -> appendChild( $xml->createElement('loc', 'http://www.airsahara.in'.$file['name']) );
$url -> appendChild( $lastmod = $xml->createElement('lastmod', date('Y-m-d', $file['lastmod'])) );
$url -> appendChild( $changefreq = $xml->createElement('changefreq', 'monthly') );
$url -> appendChild( $priority = $xml->createElement('priority', '0.5') );
// append url to urlset node
$urlset -> appendChild($url);
}
$xml->save($sitemap);
} // if time
?>
