This is a very weak tutorial. It neglects a lot of best practices (like: in templating style, keep your PHP tags on the same line). You also capitalized Echo, which is a capital offense (no pun intended) in PHP.
Wow you're only the 3 millionth to post a PHP beginners tutorial. Most here are probably more interested in howto scale PHP to 1 billion users or so (like Facebook), not to learn howto write hello world.
