here is a very basic example:
create a php page called test.php, and add the following php code into it...
<?
$var = "this is only a test";
echo "<a href='test2.php?var2=$var'>Click me!</a>";
?>
ok now I want you to mke a file called test2.php and put the following php code into it.
<?
echo $_REQUEST["var2"]." : This is the variable passed from test.php to this page test2.php";
?>
