I have the following code:

 <?php


 if ($x == 1){

 ?>
   <b>Some html...</b>
   <?php
             }
    else if ($x==2){ ?>

<b> Other html...</b>
<?php
}
?>

Now I would like to have two links below (a href) and somehow pass the variable $x (so Link1 passes x=1 and Link2 passes x=2) in order to load the relevant bit of code from if statement. I know I can pass $x using form and then test its value and load required bit of code, but I would like to do it smoothly, without reloading the page. I think that JQuery could help it, but I have no idea how to do it. Any ideas greatly appreciated.
