How can PHP functions like opendir() and readdir() be utilized in this scenario?

To list all files in a directory using PHP, you can utilize the opendir() and readdir() functions. opendir() opens a directory handle, and readdir() reads the contents of the directory handle. By looping through the directory handle using readdir(), you can list all files in the directory. 

$dir = "/path/to/directory";

if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            if ($file != "." && $file != "..") {
                echo "filename: $file : filetype: " . filetype($dir . $file) . "\n";
            }
        }
        closedir($dh);
    }
}
