Are there any specific PHP functions or libraries that can assist in displaying subpages of a website?

To display subpages of a website in PHP, you can use functions like scandir() to get a list of files in a directory, or glob() to retrieve files based on a pattern. You can then loop through the list of files and display them as links on your webpage.

<?php
$subpages_dir = 'subpages/';
$subpages = glob($subpages_dir . '*.php');

foreach ($subpages as $subpage) {
    $subpage_name = basename($subpage, '.php');
    echo "<a href='$subpages_dir$subpage_name.php'>$subpage_name</a><br>";
}
?>
