How can I dynamically retrieve the newest file in a directory using PHP?

To dynamically retrieve the newest file in a directory using PHP, you can use the `scandir` function to get a list of files in the directory, sort them by their last modified time, and then select the first file in the sorted list as the newest file. 

$directory = '/path/to/directory';
$files = scandir($directory);
$files = array_diff($files, array('.', '..')); // Remove . and .. from the list
usort($files, function($a, $b) use ($directory) {
    return filemtime($directory . '/' . $b) - filemtime($directory . '/' . $a);
});
$newestFile = $directory . '/' . $files[0];
echo "The newest file is: " . $newestFile;
