新手请教PHP限制打开目录问题!
我做了一个打开目录的PHP,其中有个返回上一级目录的功能。
请问怎么才能设置用户只能打开PHP文件所在目录及其子录,而不能返去PHP文件所在目录的上一级目录呢?即点击返回上一级的时候能返回,但最多只能返回到PHP文件所在目录而不能再返回了。
这个PHP很长,不是我写的,我就不发了,因为我也搞不明白,大家告诉我用什么函数,怎么样做就可以了,当然,越具体越好啦。

------解决方案--------------------
没有这样的函数,有也是你自己写的
既然有目录的移动,你就应该检查新目录是否有权进入
------解决方案--------------------
简单,设置执行php的进程的用户的权限即可
