PHP header

Hello, A relative PHP newbie. I have developed a system using HTML/PHP, and have had it functioning fine for some time using IIS. I am now uploading it to a web hosting service in the USA where I am firstly running a hello world page to test it. BUT! It does not want to load: <html> <head><title>Untitled</title></head> <body> <?php echo "Hello world"; ?> </body> </html> I have configured the hosting server to the best of my knowledge (setup a CGI virtual domain environment, enabled permissions etc), but it still refuses to load this rediculously simple hello world script. Can anyone tell me if the page to be executed containing the PHP script requires a pathname telling the server it is a PHP page, and if so, what is the syntax and where it is embedded in the HTML?
