取得phpcms网站下所有栏目的内容链接

今天做了一个小功能，就是取得公司网站的所有文章的内容地址，公司网站是用phpcms 做的，感觉还蛮简单的，记录下：

<?php
    $conf['DB_USER'] = 'user';
    $conf['DB_PWD'] = 'pwd';
    $conf['DB_NAME'] = 'dbname';
    $conn = mysql_connect('localhost',$conf['DB_USER'],$conf['DB_PWD']);
    if (!$conn) {
    	echo '数据库连接错误！';
    }
    mysql_set_charset('utf8', $conn);        //set charset
    mysql_select_db($conf['DB_NAME']);       //select datebase
    $sql2 = 'select catid,catname from v9_category';
    $cat = mysql_query($sql2);
    while ($catrow=mysql_fetch_array($cat)) {
    	echo $catrow['catname'].'</br>';
    	$sql = '(select title,url from v9_news where catid='.$catrow["catid"].' order by id desc)
         UNION (select title,url from v9_product where catid='.$catrow["catid"].' order by id desc)';
    	$result = mysql_query($sql);
        while ($row=mysql_fetch_array($result)) {
            echo $row['url']."</br>";
        }
    }
?>

主要是用到联合查询及双重循环。
