这是我做的删除文件的代码,删除文件的同时把他的名称从数据库中删除,现在无法实现删除文件,unlink删除文件时绝对路径吧,用dirname(__FILE__)取得本文件的据对路径,$dir是要删除的文件所在文件夹,请问哪里不对,新手求指点。文件结构是www/test5/uploadfiles/要删除文件 www/test5/delete_files.php本文件



------解决方案--------------------
先把 $a/$dir/$name 这个echo看看,地址对不
------解决方案--------------------
PHP code
$xxx = "{$a}/{$dir}/{$name}";
echo $xxx;
unlink($xxx);
<br><font color="#e78608">------解决方案--------------------</font><br>路径要对,权限要有,必须是个文件
