我根据自己博客的性质，进行了自己网站的Sitemap的开发。实现过程比较简单，效果还是比较令我满意的。关键是格式比较重要，还有在生成的过程中，有个在查看的时候，能够有个比较好的ui效果的设置。下面把我的Sitemap的生成代码记录如下：
<?php
class Sitemap extends CController{
protected $webSiteTitle = '';
protected $changefreq = '';
protected $content = '';
protected $priority = '';
protected $blogItems = array();
protected $tagItems = array();
protected $categoryItems = array();
protected $items = array();
/**
* 添加基本信息
* @param string $title
* @param string $link
* @param string $description
*/
public function __construct() {
$this->webSiteTitle = 'http://'.$_SERVER['SERVER_NAME'];
$this->changefreq = 'daily';//always hourly daily weekly monthly yearly never
$this->priority = 0.5;
}
/**
* 分类
*/
private function categorySitemap(){
$criteria = new CDbCriteria();
$criteria->condition = 'category=:category';
$criteria->params = array(':category'=>'blog');
$criteria->order = 'create_date DESC';
$result = Type::model()->findAll($criteria);
foreach($result as $k=>$v){
$this->categoryItems[] = array(
'url'=>$this->webSiteTitle.'/category/'.urlencode($v->name),
'date'=>date(DATE_W3C, strtotime($v->update_date))
);
}
}
/**
* 文章
*/
private function blogSitemap(){
$criteria = new CDbCriteria();
$criteria->condition = 'is_lock=0 and is_delete=0';
$criteria->select = 'id, tag, update_date';
$criteria->order = 'create_date DESC';
$model = Blog::model()->findAll($criteria);
foreach($model as $k=>$v){
$this->blogItems[] = array(
'url'=>$this->webSiteTitle.'/blog/'.$v->id,
'date'=>date(DATE_W3C, strtotime($v->update_date))
);
$tagArr = preg_split('#,|，#i', $v->tag);
if(!empty($tagArr)){
foreach($tagArr as $k=>$v){
if(!in_array($v,$this->tagItems)){
$this->tagItems[] = $v;
}
}
}
}
//创建临时函数数组
$tmp = array();
$tmp = $this->tagItems;
$this->tagItems = array();
foreach($tmp as $k=>$v){
$this->tagItems[] = array(
'url'=>$this->webSiteTitle.'/tag/'.urlencode($v),
'date'=>date(DATE_W3C, time())
);
}
unset($tmp);
}
/**
* 构建xml元素
*/
public function buildSitemap() {
$blogitem = '';
foreach($this->blogItems as $k=>$v){
$blogitem .= <<<BLOG
<url>\r\n
<loc>{$v['url']}</loc>\r\n
<lastmod>{$v['date']}</lastmod>\r\n
<changefreq>{$this->changefreq}</changefreq>\r\n
<priority>{$this->priority}</priority>\r\n
</url>\r\n
BLOG;
}
$categoryitem = '';
foreach($this->categoryItems as $k=>$v){
$categoryitem .= <<<BLOG
<url>\r\n
<loc>{$v['url']}</loc>\r\n
<lastmod>{$v['date']}</lastmod>\r\n
<changefreq>{$this->changefreq}</changefreq>\r\n
<priority>{$this->priority}</priority>\r\n
</url>\r\n
BLOG;
}
$tagitem = '';
foreach($this->tagItems as $k=>$v){
$tagitem .= <<<BLOG
<url>\r\n
<loc>{$v['url']}</loc>\r\n
<lastmod>{$v['date']}</lastmod>\r\n
<changefreq>{$this->changefreq}</changefreq>\r\n
<priority>{$this->priority}</priority>\r\n
</url>\r\n
BLOG;
}
$this->content = <<<SITEMAP
<?xml version='1.0' encoding='UTF-8'?>\r\n
<?xml-stylesheet type="text/xsl" href="{$this->webSiteTitle}/sitemap.xsl"?>
<!-- generator="GoWhich/1.0" -->
<!-- sitemap-generator-url="{$this->webSiteTitle}" sitemap-generator-version="1.0.0" -->
<urlset xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"\r\n
xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd"\r\n
xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">\r\n
{$blogitem}
{$categoryitem}
{$tagitem}
</urlset>\r\n
SITEMAP;
}
/**
* 输出sitemap内容
*/
function show() {
$this->blogSitemap();
$this->categorySitemap();
if (empty($this->content)) {
$this->buildSitemap();
}
return $this->content;
}
/**
* 将rss保存为文件
* @param String $fname
* @return boolean
*/
function saveToFile($fname) {
$handle = fopen($fname, 'wb');
if ($handle === false){
return false;
}
fwrite($handle, $this->content);
fclose($handle);
}
/**
* 获取文件的内容
* @param String $fname
* @return boolean
*/
function getFile($fname) {
$handle = fopen($fname, 'r');
if ($handle === false){
return false;
}
while(!feof($handle)){
echo fgets($handle);
}
fclose($handle);
}
}
?>
Controller中我建立了两个action
/**
* sitemap列表
*/
public function actionSitemap(){
//rss创建
$obj = new Sitemap();
$this->render('sitemap',array('rss'=>$obj->show()));
}
public function actionSitemapXsl(){
$this->render('sitemapxsl');
}
View的两个文件的代码如下
sitemap.php
<?php
/* @var $this FeedController */
header("Content-Type: text/xml; charset=utf-8");
echo $rss;
exit;
?>
sitemapxsl.php
<?php
header("Content-Type: text/xml; charset=utf-8");
?>
<?php
$xml = <<<XML

为了使得url看起来好看一点。
我做了一下路由设置
'sitemap.xsl'=>'site/sitemapxsl',
'sitemap.xml'=>'site/sitemap',
