PHP Convert Files To Lowercase

I am struggling with the syntax and logic, could someone help me with this question: 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>'  '</h3>';
  }
}
echo($file);
?>

You need to get the contents of the file and then use strtolower:

<?php
//add code here
$files = scandir('example');
foreach($files as $file){
  if(strpos($file, 'fun') === false){
    //do nothing
  }else{
    echo "<h3>$file</h3>";
    echo strtolower(file_get_contents('example/'.$file));
  }
}
