php基础练习--目录遍历：
![]()
("content-type:text/html;charset=utf-8" = "./final/factapplication" listdir( = ( ( !== ( = ( = .'/'. ( != '.' && != '..' (( ."
"();
listdir
核心：递归的经典应用，以及文件和目录的基本操作。
![]()
= "../fileupload" = "b" copydir(, ( = ( ( !== ( = ( = ."/". = ."/". ( != "." && != ".." ((, (, (, );
copydir
核心：copy函数。
![]()
= 'a' deldir( = ( ( !== ( = ( = .'/'.( != '.' && != '..' (((( ();
deldir
核心：注意unlink删除的是带path的file。
![]()
= "a" dirsize( = ( ( !== ( = ( = .'/'. ( != '.' && != '..'(( = + ( ( dirsize();
dirsize
核心：通过判断$tot在哪里返回，理解递归函数。
