PHP中的目录遍历功能本来也很普通,但它却具有一种"面向对象"的形式, 所以也提一下:
(1)dir, opendir
用法:
$d = dir("目录名");
$handle = opendir("目录名");
前者返回一个目录对象,后者返回一个目录句柄. 前者返回的对象有handle和path两个属性,第一个就相当于opendir 返回的句柄,第二个就是目录名本身.访问时用$d->handle和$d->path.

(2)read, readdir, rewind, rewinddir, close, closedir
三组中每组的前一个是目录对象的方法,用"对象->方法()"调用, 后一个是函数,用"函数名(目录句柄)"调用. read是返回目录中的下一个文件名. rewind是回到目录的第一个文件名. close是关闭目录,不再遍历.

(3)chdir
转换PHP的工作目录.
