Simple Question about PHP

I started learning PHP to create a simple website i'm planning.
I have a simple Question:

I have omitted some code to be specific about the point. The code is from chapter 13 of wrox Beginning PhP 5.3.
What i want to know is, why do we have stray "<?" tags? e.g:
Also, why is there PHP snippet after </html> tag?
I think this is a question anybody with server-side scripting can answer

They are not stray tags. Each ?> belongs to a corresponding <?php tag.

Inside a <?php ?> block, your php code is executed. Anything outside a php block is directly emitted to the resulting html.

The mind is a strange and wonderful thing. I'm not sure that it will ever be able to figure itself out, everything else, maybe. From the atom to the universe, everything, except itself.

This is html/php code which means you have to seperate the two in the code so the server knows which part of the code belongs to it and which he will pass on to the clients browser, you do that by putting php inside <?php ?> tags.
Remember php is server-side while html is client-side, what the server sees and actually matters to it is this:
