For each of the files whose name contained "fun", convert the contents of the file to lowercase and display the lowercas

I do not see where is the error, for my it's ok..

index.php
<?php
$files = scandir("example");

 foreach($files as $file) 
 { if (strpos($file,"fun",0) !== false) 
 { echo  '<h3>' . $file . '</h3>'; 
  echo strtolower($file);

<?php $files = scandir("example");

foreach($files as $file) { if (strpos($file,"fun",0) !== false) { echo '<h3>' . $file . '</h3>'; echo strtolower("$file <br>"); <----------- I added this line thinking the problem was that bus is still the same

}

else{ echo $file; } } ?>

Hi guys, The question is about displaying the content of the matching files. so you have to read the content og the files. One way to do this by using the file_get_contents function and supplying the path to each file inside the loop: $content= file_get_contents("example/".$file); Then you can convert the content to lowercase and printing its value. echo strtolower($content); I hope that would help :-)
