Are there any specific PHP core functions or classes that can help in managing directory paths effectively to avoid long and cluttered expressions?

When managing directory paths in PHP, it can be helpful to use the `realpath()` function to resolve any symbolic links and get the absolute path of a directory. Additionally, the `DIRECTORY_SEPARATOR` constant can be used to ensure platform-independent directory separator characters are used in paths. By using these functions, you can effectively manage directory paths and avoid long and cluttered expressions. 

// Example of using realpath() and DIRECTORY_SEPARATOR to manage directory paths
$dir = '/path/to/directory';
$absolutePath = realpath($dir) . DIRECTORY_SEPARATOR;
echo $absolutePath;
