I was just reading the PHP 10.0 Blog when I saw a post called dirname(__FILE__). It’s a call for a new constant that provides the directory of the current file. Personally I think this is a brilliant idea and it shouldn’t be discouraged just because legacy applications will need to use dirname(__FILE__) instead of the new constant. Eventually those versions will disappear. After all, who still writes code that’s backwards compatible with PHP 3?

Let’s get this in now for PHP 6!!
