Are there any specific PHP functions or methods that can help with including folders?

To include folders in PHP, you can use the `glob()` function to retrieve an array of files within a directory and then loop through the array to include each file. This allows you to include all PHP files within a specific folder without having to manually list each file.

$folder_path = 'path/to/folder/';

foreach (glob($folder_path . '*.php') as $file) {
    include $file;
}
