Returning the name of the php file

[karlovac]

Is there some way of returning the name of the current php file from the script?

e.g.

I have a file called index.php. How can I get PHP to figure out that the file is "index.php", so that I can assign that to a variable?

Thanks,

The name of a file can be returned to your PHP script using the FILE constant; note there are 2 underscores. Additionally, each line in a PHP file is referred to with the LINE constant.

The FILE will return the full, absolute path to the script; i.e. "/home/jake/php/index.php", NOT the URL. If you're only interested in the filename (without the path information), simply trim it, using the basename() function: basename(FILE).

Hey Dar

Thanks for your reply - it works great!

I was wondering: is this constant going to slow the page down at all, or is it quite light on the server?

This value is an internal PHP constant; it'll be available whether you use it or not. Since it's already there, it's impact on the server should be negligible.
