php生成sitemap的类(class)其实很简单，但为了方便还是写成了一个类，附php生成sitemap的类文档下载以及示例说明
<?php
/***************************************
$文件名: class.sitemap.php $
$描述: php生成sitemap类$

****************************************/
class sitemap {
var $charset = "UTF-8";
var $s = "";
function sitemap($encoding = '') {
if(empty($encoding)){
$encoding = "UTF-8";
}
$this->s = "<?xml version=\"1.0\" encoding=\"$encoding\"?>\n";
$this->s .= "<urlset xmlns=\"http://www.google.com/schemas/sitemap/0.84\">\n";
}
/*****************
* $loc url地址 符号要转义
符号 & &
单引号 ' '
双引号 " "
大于 > >
小于 < <
* $lastmod 修改时间 W3C Datetime 可以使用YYYY-mm-dd
* $changefreq 更新频率 always hourly daily weekly monthly yearly never
* $priority 重要性 0.1-1.0之间
*******************/
function addurl($loc, $lastmod = '', $changefreq = '', $priority = '') {
$loc = htmlentities($loc,ENT_QUOTES);
$this->s .= "\t\t<url>\n\t\t\t<loc>$loc</loc>\n";
if(!empty($lastmod)){
$this->s .= "\t\t\t<lastmod>$lastmod</lastmod>\n";
}
if(!empty($changefreq)){
$this->s .= "\t\t\t<changefreq>$changefreq</changefreq>\n";
}
if(!empty($priority)){
$this->s .= "\t\t\t<priority>$priority</priority>\n";
}
$this->s .= "\t\t</url>\n\n";
}
function buildsitemap($filename = "") {
$this->s .= "\t</urlset>\n";
if(empty($filename)){
header("Content-Type: text/xml");
echo $this->s;
}else{
$this->save2file($filename);
return true;
}
}
function save2file($filename) {
$fp = @fopen($filename,"w+") or die(sprintf("建立文件1%失败",$filename));
@fwrite($fp,$this->s);
@fclose($fp);
}
}
?>
