I suggest that you get a basic PHP tutorial rather than trying to figure
out how things work, it'll be less frustrating.

About your question, you can generate HTML just typing it outside the PHP
tags:

<?php

// This is PHP

?> This is HTML

Or you can use echo or print statements:

<?php

echo 'This is HTML dynamically generated from PHP';

?>

You read URL parameters from the $_GET associative array:

echo 'Param a=' . $_GET['a'];

Re: variables

You can use POST or GET to "send variables" to the next page.

GET is what you have listed in your question.

eg. index2.php?a=0& b=1&c=2

POST is when you use a form. From the PHP web site:

When a form is submitted to a PHP script, the information from that
form is automatically made available to the script. There are many ways
to access this information, for example:

Example 12-8. A simple HTML form

<form action="foo.php " method="post">
Name: <input type="text" name="username" /><br />
Email: <input type="text" name="email" /><br />
<input type="submit" name="submit" value="Submit me!" />
</form>

You may get the POST 'username' variable (from the form above) by using
these
$_POST['username'];
$_REQUEST['username'];

You may retrieve the GET variable 'a' (from index2.php?a=0& b=1&c=2)
by the using these
$_POST['a'];
$_REQUEST['a'];

Really? The PHP website said that?
It should have said:

You may retrieve the GET variable 'a' (from index2.php?a=0& b=1&c=2)
by the using these
$_GET['a'];
$_REQUEST['a'];
