帮忙看下代码是否正确,删除一个月前的数据和文件。
理论上代码是正确的,但是怕个万一……
文件、数据删错了就不好玩了……
高手们,帮忙看下下面的代码正确与否?

PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->require (dirname(__FILE__) . "/../conn.php");mysql_select_db("news",$conn_database);mysql_query("delete from web_news where news_date
Copy after login


------解决方案--------------------
filectime
应改为
filemtime

你可以注释掉 unlink(dirname(__FILE__).'/../cache/'.$file);
改为
$fn = dirname(__FILE__).'/../cache/'.$file;
echo $fn . ' - ' . filemtime($fn);
先查看一下
------解决方案--------------------
忽略了,没注意还有数据库的
(date(now())-60*60*24*30)
改为
DATE_SUB(now(),INTERVAL 30 DAY)

同样已是先 select 确认一下
