How can PHP be used to sort image files based on their modification time and display the newest one?

To sort image files based on their modification time and display the newest one, we can use PHP's `glob()` function to get a list of image files in a directory, then use `filemtime()` to get the modification time of each file and sort them accordingly. 

$files = glob("path/to/images/*.{jpg,jpeg,png,gif}", GLOB_BRACE);
usort($files, function($a, $b) {
    return filemtime($b) - filemtime($a);
});

$newestImage = $files[0];

echo '<img src="' . $newestImage . '" alt="Newest Image">';
