are you asking what is the meaning of an index in php as in index.php? index.php is the default file the web server will load if you don't indicate a file and only a folder. if your web site was example.com, and you make a subdirectory called /test, then if you wanted a script to run when they type www.example.com/test, then you would make a file called index.php and put it in the subdirectory called test. same is true with .html files
