Here is the simple code to list all files and directory present in a directory.
Listing all files and directory of current folder
Listing all files and directory of up folder
We can develop a small script which will first list file and directory of current directory. All listed directory will have hyperlink to list files and directory present inside that on click. We have used is_dir function to check if the output string is a directory or not.
Travelling to different subdirectory and up directory structureAbove script we will modify to provide option where users can click folders to visit those folders. They can move upward ( towards root ) or can move downward by travelling to different levels deep inside the folder structure. Here is the code to do that.
Emptying folders by deleting all filesThis is the best way to empty the files in a folder to delete the folder. This script will keep on deleting files as you move on different level of folders.
Be warned that as you are going to delete the files not only of current folder but of all other folders you try to visit.
We kept the delete command commented for safety reasons and after understanding all the consequences you can un comment the line and use it at your own risk.
