Have each link have a GET variable after it.

$clickedon = $_GET['clickedon'];

if(isset($clickedon)) {

   echo "You clicked on ".$clickedon;
   echo "<br><A href=\"thispage.php\">Try again?</a>";

} else {

   echo "<a href=\"thispage.php?clickedon=button1\">Click here for option 1</a>";

   echo "<a href=\"thispage.php?clickedon=button2\">Click here for option 2</a>";

}
