经典帝国CMS生成sitemap实现代码分享

因为对帝国CMS的sitemap插件不太满意，所以自己写了个sitemap生成工具，在sitemap中放了首页链接、栏目页链接和内容页链接，然后生成XML文件并且提交到百度站长工具，本文中的代码是需要生动生成的，我自己是在Linux中用cron写的定时任务，每天固定时间生成一次，先这样吧~

代码如下:

<?php/*引用文件*/require('e/class/connect.php');require('e/class/db_sql.php');require('e/data/dbcache/class.php');</p> <p>/*建立数据库链接 与 实例化类*/$link = db_connect();$empire=new mysqlquery(); </p> <p>//header("Content-type:application/xml");header("Content-type: text/html; charset=utf-8");</p> <p>$operation = $_GET['operation'];$current_url = explode('/',$_SERVER['PHP_SELF']);$current_script_name = end($current_url); </p> <p>if($operation && $operation == "makexml"){$xml = generate_sitemp_xml();$result = save_xml('sitemap.xml',$xml);if($result){echo '生成成功，<a href="sitemap.xml">点此查看</a>';}else{echo '生成失败，<a href="'.$current_script_name.'">在来一次</a>！';}}else{echo '欢迎使用微笑的鱼Sitemap生成工具，请<a href="'.$current_script_name.'?operation=makexml">点此生成</a>！';}</p> <p></p> <p>//保存到文件function save_xml($filename, $text) {if (!$filename || !$text)return false;@chmod($filename,0777);if ($fp = fopen($filename, "w")) {if (@fwrite($fp, $text)) {fclose($fp);return true;} else {fclose($fp);return false;}}return false;}//生成Sitemap XML数据function generate_sitemp_xml(){global $dbtbpre,$empire;$xml = '';$xml .= '<?xml version="1.0" encoding="utf-8"?>' .PHP_EOL;$xml .= '<urlset>' .PHP_EOL;$xml .= generate_home_xml();//首页$xml .= generate_class_xml();//栏目$query="select * from {$dbtbpre}ecms_news order by id desc limit 100";$sql=$empire->query($query);while($r=$empire->fetch($sql)){$titleurl=sys_ReturnBqTitleLink($r);$xml .= ' <url>' .PHP_EOL;$xml .= ' <loc>'.$titleurl.'</loc>' .PHP_EOL;$xml .= ' <lastmod>'.strftime('%Y-%m-%d',$r['newstime']).'</lastmod>' .PHP_EOL;$xml .= ' <changefreq>daily</changefreq>' .PHP_EOL;$xml .= ' <priority>0.8</priority>' .PHP_EOL;$xml .= ' </url>' .PHP_EOL;}$xml .= '</urlset>' .PHP_EOL;return $xml;}//生成栏目链接XML数据function generate_class_xml(){global $dbtbpre,$empire,$class_r;$xml = '';$sql=$empire->query("SELECT * FROM {$dbtbpre}enewsclass WHERE islast=1");while($r=$empire->fetch($sql)){$infor=$empire->fetch1("SELECT newstime FROM {$dbtbpre}ecms_".$class_r[$r[classid]][tbname]." WHERE classid='$r[classid]' ORDER BY newstime DESC LIMIT 1");$class_url=sys_ReturnBqClassname($r, 9);$xml .= ' <url>' .PHP_EOL;$xml .= ' <loc>'.$class_url.'</loc>' .PHP_EOL;$xml .= ' <lastmod>'.strftime('%Y-%m-%d',time()).'</lastmod>' .PHP_EOL;$xml .= ' <changefreq>daily</changefreq>' .PHP_EOL;$xml .= ' <priority>0.8</priority>' .PHP_EOL;$xml .= ' </url>' .PHP_EOL;}return $xml;}//生成栏目链接XML数据function generate_home_xml(){$xml = '';$xml .= ' <url>' .PHP_EOL;$xml .= ' <loc>https://www.jb51.net</loc>' .PHP_EOL;$xml .= ' <lastmod>'.strftime('%Y-%m-%d',time()).'</lastmod>' .PHP_EOL;$xml .= ' <changefreq>daily</changefreq>' .PHP_EOL;$xml .= ' <priority>0.8</priority>' .PHP_EOL;$xml .= ' </url>' .PHP_EOL;return $xml;</p> <p>}</p> <p>/*关闭数据库连接 与 释放类*/db_close();$empire=null;?
