I think this is the one of the causes of confusion. HTML is written
directly into a PHP file. :)

Ash is correct.
More specifically, PHP code delivers web languages to a user's
Browser.
The Browser never actually see’s PHP scripts because PHP runs on the
server (not the client) and delivers what it wants to the Browser
via client-side web languages (i.e., HTML, CSS, JavaScript et al).
In other words, by the time the Browser see’s anything, PHP is
finished.

O.K. this is another way of looking at it.
But as I understand it, when the web server is asked to produce a
resource in the form of a text file with a .php extention
the raw html/css/javascript it sees it delivers directly. When it sees
opening and closing php tags it hands that
off to the php interpreter which then returns the result to the
server. Then the server delivers the result of the
php code processing. In files that are included, that have no html,
nothing is sent to the client unless there is
a print or echo statement in that file. With a print or echo statement
it is still the server which sends it as html
and text. It is possible to have a resource with a php extention, that
has no php code in it, only html/css/javascript.
That would get sent.
