From the PHP documentation, the difference is that $_SERVER['SCRIPT_FILENAME'] contains the absolute path to the current script, and in CLI mode, may contains a relative path.

__FILE__ will contains you the path of included file if used inside an included file, or the path of main file if used inside the main file.

Blackquoting from http://www.qualitycodes.com/tip/17/difference-between-serverscriptfilename-and-file.html:

$_SERVER['SCRIPT_FILENAME'] variable will return same path whether it is used in the main file or in an included file on the other hand __FILE__ variable will return you the path of included file if used inside an included file and the path of main file if used inside the main file. I am referring to main file the one whose name is displayed in the address bar of browser.
