No, PHP is executed from top to bottom, it will only include those pages it's
told to include depending on the condition. In your switch example, there
would be at most one file included (no default, so there can be time no file
is included).

There are many who uses dynamically included files, take a look at phpnuke for
one example, I'm not that much for this, so you have to look this up yourself.

Much depends on how you want things to work, you know freedom.

$thewholeresult=shell_exec('php yourphpfile.php');

but include is a lot better, as you can easily get the variables you got to
the main page to the included file, which is a little bit more tricky with
header() or execute another php file through a shell.
