How can PHP be used to sort and load files based on date in a dynamic file inclusion scenario?

When dynamically including files based on date in PHP, you can use the `scandir()` function to get a list of files in a directory, sort them by date using `usort()`, and then include them in the desired order. Here is a sample code snippet that demonstrates this approach:

$dir = 'path/to/directory/';
$files = scandir($dir);
usort($files, function($a, $b) use ($dir) {
    return filemtime($dir . $a) < filemtime($dir . $b);
});

foreach($files as $file) {
    if ($file != '.' && $file != '..') {
        include $dir . $file;
    }
}
