It will 'see' the variables the same way any code written after those
variables were declared could see them - a PHP 'include('');' takes the file
and mixes it in, almost like a copy and paste job of the file contents. Give
it a go, you'll notice it works.
Appending variables onto the URL is a method of sending variables across
pages, it is called 'GET' and another method is called 'POST' - have a read
at php.net.
To demonstrate GET, try this code by itself:
<?php echo $_GET['arg']; ?>
Now view the webpage and append ?arg=hello onto the end of the URL. You can
change arg to equal anything and it will display on the page.
Usually you wouldn't use GET unless you needed to, because the whole world
can see your variables in the address bar, and therefor can reassign them by
editing the URL. This opens your PHP script up to manipulation. However GET
is still pretty handy for times when you want to send variables to another
page through, say, a link, since POST only works through an HTML form. A
whole row of links like <a href=nextpage.php?arg=hello>Say Hello</a> but
with different values for 'arg' - you've only made 1 PHP file called
nextpage.php, but if it's recieving a $_GET['arg'] value you've got an
almost limitless amount of different permutations for that page (dynamic).
