What are the advantages of using __DIR__ over __FILE__ when including files in PHP scripts?

Using __DIR__ instead of __FILE__ when including files in PHP scripts provides more flexibility and reliability, especially when dealing with file paths. __DIR__ returns the directory of the current script, which can be useful when including files from different directories or when the script is included in another file. This approach helps avoid issues related to relative paths and makes the code more portable.
