hey guys,

All I know is HTML and today I tried to write a PHP file with notepad.
Well, since my laptop doesn't have IIS, I couldn't install PHP on my computer. (I have XP home edition)

Now I signed up for Free Hosting, and after I wrote on Index.html,

<html>
<body><?php echo "Hello World"; ?></body>
</html>

it didn't show up.
So, do I manually install PHP program on my web space ?
on file manager, all I have is just index.html.

I know nothing about PHP, so please help me to figure this out.
Thanks guys ! =)
