Varable change with onclick

[lamboman]

I have 3  images Shown below. What I want to do is add an onclick that will change another variable (lets call it $secondary). So when any one of these are clicked it will change the variable $secondary to whatever I want it to be. (hope that makes sence)

 

<?php

$main[0]="<img src='images/00.gif'>";

  echo $main[0];

?>

    <?php

$main[1]="<img src='images/01.gif'>";

  echo $main[1];

?>

    <?php

$main[2]="<img src='images/02.gif'>";

  echo $main[2];

?>

onclick is a client side event caught by client side languages like javascript. PHP can't do anything with an onclick event.
