Hello all,

Please tell me the difference of $_SERVER['SCRIPT_NAME'] and $_SERVER['PHP_SELF']. I read PHP Docs from php.net but I cannot understand.

If both is the same, which should I use for better performance?

Thanks a lot!

$_SERVER['PHP_SELF']

This is the filename of the currently executing script, relative to the document root. However, unlike $_SERVER['SCRIPT_NAME'], it provides additional path information like $_SERVER['REQUEST_URI'] when the actual php file is present in the path. So when the $_SERVER['REQUEST_URI'] is /index.php/big/directory/ then $_SERVER['PHP_SELF'] will beHowever if all the URI's under http://www.example.com/ is mapped to http://www.example.com/index.php, then, for example, http://www.example.com/abc/def will return like $_SERVER['SCRIPT_NAME']. Note that $_SERVER['REQUEST_URI'] data is ignored for this request.

I often get confused as to which I should be using. It would be nice to have a better solution -- if that is possible.
