很简单的修改了 原phpcms自带的 生成xml的程序文件 ，

原来的生成程序文件是 /phpcms/modules/admin/googlesitemap.php

修改这个文件放到根目录下命名为sitemap.php，代码如下：

if(PHP_SAPI != 'cli')

{

header('location: sitemap.xml');

exit;

}

define('PHPCMS_PATH', dirname(__FILE__).DIRECTORY_SEPARATOR);

include PHPCMS_PATH.'phpcms/base.php';

pc_base::load_sys_class('form', '', 0);

class gbsitemap {

function __construct() {

$this->header = "\n\t";

$this->charset = "UTF-8";

$this->footer = "\t\n";

$this->baidunews_footer = "";

$this->items = array();

$this->baidunew_items = array();

//生成栏目级别选项

$this->siteid = 1;

$this->categorys = getcache('category_content_'.$this->siteid,'commons');

}

function add_item2($new_item) {

$this->items[] = $new_item;

}

function build( $file_name = null ) {

$map = $this->header . "\n";

foreach ($this->items AS $item){

$map .= "\t\t\n\t\t\t$item[loc]\n";

$map .= "\t\t\t$item[changefreq]\n";

$map .= "\t\t\t$item[priority]\n";

$map .= "\t\t\n\n";

}

$map .= $this->footer . "\n";

if (!is_null($file_name)){

return file_put_contents($file_name, $map);

} else {

return $map;

}

}

function google_sitemap_item($loc, $lastmod = '', $changefreq = '', $priority = '') {

$data = array();

$data['loc'] = $loc;

$data['lastmod'] = $lastmod;

$data['changefreq'] = $changefreq;

$data['priority'] = $priority;

return $data;
