File Handling with PHP

Why this is not correct (Challenge Task 2 of 3) ?

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

foreach($files as $file){ echo '<h3>'; if(substr($file, 0,3) == 'fun'){ echo $file; } echo '</h3>'; }

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

foreach($files as $file){
  echo '<h3>';
  if(substr($file, 0,3) == 'fun'){
    echo $file;
  }
  echo '</h3>';
}

Hi Tome, you're not looking for files that begin with the string fun, but files that contain fun anywhere in the name. Using the strpos() function makes the most sense in this case, not the substr() function.

if (strpos($file, 'fun') !== false) {
    // do something with $file
}

You also have to make sure that you're only echoing out the H3 tags inside your conditional check, otherwise the H3 tags will printed out, even though the condition isn't true.
