how do I loop thru a directory with several levels of subdirectory?

Hi, how do I loop thru a directory and store all file names into array.

For example:
Folder 1 (root folder)
---Folder 1.1
-----test3.txt
-------Folder 1.1.1
---------test3.txt
---Folder 1.2
-----test4.txt
--test.txt
--test2.txt

So maybe the end result will be:
array[0] = "Folder 1/test.txt";
array[1] = "Folder 1/test2.txt";
array[2] = "Folder 1/Folder 1.1/test3.txt";
array[3] = "Folder 1/Folder 1.1/Folder 1.1.1/test3.txt";
array[4] = "Folder 1/Folder 1.2/test4.txt";

Use recursion. Basically put your code into a function, and then use is_dir to check if the current file is a directory. If it's a directory, call the function itself again. Something like:

function scanDir($dir) {
  $d = opendir($dir);
  while (...) {
     if (is_dir($file)) {
        scanDir($dir . '/' . $file);
     } else {
         // put in array
     }
   }
}

Hi thanks alot for that. It works.

Now there's another smaller problem.
Now that I've manage to store all their file path into array. I will loop thru that array and then use the rename() to move those files to another place. So at the end of the process, what's left behind all the several level of empty subfolder.

Using the resursive loop, how do I loop thru and delete everything give a directory. All are just empty sub folders.

Instead of puting the the files into an array use [man]unlink[/man] to delete the files.

If you want to remove the directories use [man]rmdir[/man]

If you are doing both at the same time make sure your recursive function removes files in a dir before removing the dir itself.
