As well as I know it, PHP doesn't know anything about HTML.
It doesn't know any HTML tags, what is inside and what isn't.

That does make it interesting to write an HTML page about PHP.

<title> The <?php and ?> tags.</title>

It reads along until it finds <?php which might be inside something else.

Next question, though, how does it know where the end is?  How about:

"'"'<?php echo "closing PHP?>"; ?>'"'" 

Once it is parsing PHP, I presume it knows what PHP quotes look like.
