新手求解include_path问题？
add.php与conn.php在同一个文件夹里。。

Warning: include(../conn.php) [function.include]: failed to open stream: No such file or directory in E:\wwwroot\bbs1\add.php on line 3

Warning: include() [function.include]: Failed opening '../conn.php' for inclusion (include_path='.;C:\php5\pear') in E:\wwwroot\bbs1\add.php on line 3

这是什么原因？求解。。。
