How can PHP be used to dynamically generate and display file listings within specified folders on a website?

To dynamically generate and display file listings within specified folders on a website using PHP, you can use the `scandir()` function to get an array of files in the specified folder. Then, you can loop through the array and display each file as a link on the webpage.

<?php
$folder = "path/to/your/folder";
$files = scandir($folder);

foreach ($files as $file) {
    if ($file != "." && $file != "..") {
        echo "<a href='$folder/$file'>$file</a><br>";
    }
}
?>
