PHP-GTK Community : a community site for PHP-GTK

Hi, I am a newbie to php-gtk and programming in general, I have done some stuff building web pages, joomla templates. First to say that I have got php-gtk 2 up and running doing simple "hello world" things on Windows XP SP2 and I think it is fantastic.

However, I can't seem to work out how to run a php gtk 2 application/script on my mac.

I have a Macbook running OS X Leopard.

I have download php-gtk 2.0.0.dmg as per the installation tutorial by Anant on this site (http://php-gtk.eu/install-phpgtk-2-on-macos-x)

I have followed the tutorial instructions and it says it has installed correctly.

I have then got myself a 'hello world' example and saved it as hello.phpw

and here comes the stupid question: how do I run the hello.phpw file.

Thanks in advance
Michael
