$_POST = POST Requests (normally from a form)

$_GET= Get Requests (from the URL) or a form

$_REQUEST Either Get or Post Requests

How would PHP include something in a URL?

example

<?php
echo "Data=".$_GET['data'];
echo "<br>";
echo "ID=".$_GET['id'];

$newid = ($_GET['id'] + 1);
echo "<a href='example1.php?id=$newid&data=test'>test</a>";
?>
