what's the difference between SCRIPT_FILENAME and SCRIPT_NAME?

I tried to search for a difference but each time the vars a开发者_JAVA百科re identical, any ideas ?

Based on my understanding of this, they can be different if you're executing through the command line (CLI).

Check THIS Difference:

• script_filename returns REAL DIR C:/xampp/htdocs/demo/index.php

• file returns LOGIC JUNKTION D:\www\local\demo\cms\init.php

Hold that in mind when checking pathes
