File to lowercase

For each of the files whose name contained "fun", convert the contents of the file to lowercase and display the lowercase version after each H3 title.

index.php 
<?php
//add code here
$dir = 'example';
$files = scandir($dir);
foreach ($files as $file) {
  if (strpos($file, 'fun') !== false) {
    echo '<h3>';
echo strtolower(file_get_contents($dir . '/'. $file));
  }
}
