在XML页面中使用PHP进行RSS

Question

I would like to know if it is possible to use Php coding in a xml page that is used for rss. Basically I want to connect to mysql database and pull out information to be in the rss feed as shown;

while($r = mysql_fetch_object($sql_rss)){

    $post_title = $r->title;
    $post_post = $r->thepost;
    $post_link = $r->thelink;

    $received_posts .= '
<title>'.$post_title.'</title>
<link>'.$post_link.'</link>
<description>'.$post_post.'</description>';

Would I need to do anything special to use php in a xml script? Thanks in advanced.

只要确保服务器正在为PHP指令处理文件（可能通过在文件名末尾使用.php ）并设置Content-Type（因为它默认为HTML）即可。

header('Content-Type: application/rss+xml');
