Dear All,

I was looking for advanced PHP OO programming tutorials and came
across www.afascripts.com.

They present nice tutorials, but one thing puzzled me: in some of the
code there are backslashes before function names, e.g.:

\spl_autoload_register(array($autoLoader, 'load'));
\class_exists($classname) || \interface_exists($classname)){
if (\file_exists($file)){

(have a look at http://www.afascripts.com/2011/01/07/basics-1-autoloading/#respond).

What does the backslash before the function name do?

Regards,
George

It's a PHP 5.3 feature:
