How can the readdir() function in PHP be used to read files in a folder and display them in reverse order?

To read files in a folder and display them in reverse order using the readdir() function in PHP, you can store the filenames in an array while reading them and then use array_reverse() function to reverse the order before displaying them.

php 
$dir = "path/to/folder";
$files = array();

if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            if ($file != '.' && $file != '..') {
                $files[] = $file;
            }
        }
        closedir($dh);
    }
}

$files = array_reverse($files);

foreach ($files as $file) {
    echo $file . "<br>";
}
