Hello Michael , I just do a live coding for you. I use DirectoryIterator function on PHP and Iterate to directory.

If it is dot such as "." , ".." it would continue without adding it to array because these aren't real filename. It would usually caused problem when working with files. If it isn't a dot , It is a working filename so I add it to array.

Thank you

$path = "YourFilePath";
$files = array();
foreach (new DirectoryIterator($path) as $file) {

 if ($file->isDot()) {
       $files[] = $file->getFilename();

Edited :

I thought it is a custom code.

For Challenge Code :

//add code here
$files = scandir("example");
foreach($files as $file){
  echo "<h3>$file</h3>";
    echo strtolower(file_get_contents("example/".$file,true));
