Your array variable is empty because you declared it but you didn't do anything with it.

You have to use one of the PHP directory functions to look for the files. Go to the first video and and take a look at the teacher's notes and also take a look at the "File Handling Cheat Sheet".

  • chdir — Change directory
  • chroot — Change the root directory
  • closedir — Close directory handle

  • opendir — Open directory handle
  • readdir — Read entry from directory handle
  • rewinddir — Rewind directory handle
  • * scandir — List files and directories inside the specified path *
