I am trying to display all folders and sub folders of a directory and recurse through the sub directories also.
My structure is
Folder a
a1
a11
a11.txt
a12
a2
a21
a22
a22.txt
a.txt
Folder b
b1
b11
b11.txt
b12
b2
b21
b22
b22.txt
b.txt
If I select level 1 only 1 level of hierarchy should be displayed, if i select 0 all the levels will be displayed. But will display only directories. I’m new to PHP. Please help me out!!!
