关于目录遍历,结果为树形结构的问题,请高手指点下
我想递归遍历一个目录,然后让结果呈树形结构展示出来,请高手指点下。下面是遍历函数

PHP code

Copy after login


如何让他以树形结构显示呢?
a -- dir
 a.tx
 a1.exe
 a1 -- dir
  aa.txt
  bb.exe
b --dir
 b2 -- dir
 b3 -- dir
  b3b.txt
  b4g.exe
..........

------解决方案--------------------
在 echo 后面插入 str_repeat(' ', substr_count($path, '/')) .
