Files Containing "fun" 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));
  }
}

You've got the hard part done with using the NOT IDENTICAL operator (!==) for strpos().

You only need to echo out the file name. Currently you're echoing the actual contents of the file (and you don't need to use strtolower()). You are also missing the closing h3 tag.
