What steps can be taken to troubleshoot issues with integrating a select dropdown menu with PHP directory listing code?

Issue: The select dropdown menu is not populating with the directory listing data from PHP code. Solution: Ensure that the PHP code is correctly retrieving the directory listing data and formatting it properly for the select dropdown menu. Check for any errors in the PHP code that may be preventing the data from being displayed correctly. 

<?php
$dir = "./"; // Directory path
$files = scandir($dir); // Get list of files in directory

echo "<select>";
foreach ($files as $file) {
    if ($file != "." && $file != "..") {
        echo "<option value='$file'>$file</option>";
    }
}
echo "</select>";
?>
