In PHP scripts that list folder contents and files, how can the contents of a folder be displayed when clicking on the folder name, and what modifications are needed to achieve this functionality effectively?

To display the contents of a folder when clicking on the folder name in a PHP script, you can use the opendir() function to open the directory, readdir() function to read the contents of the directory, and closedir() function to close the directory. You can then display the contents using a loop to iterate through the files and folders. 

<?php
$dir = "./folder_name";

if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            if ($file != '.' && $file != '..') {
                echo "<a href='$dir/$file'>$file</a><br>";
            }
        }
        closedir($dh);
    }
}
?>
