use a Link to call a function

[Bogie]

Hi there,
I need to use a text link (like href) - not a button!! - to call a function. How do I have to code this?
I've absolutely no idea.

Please help me.

Thanks in advance
Bogie

<a href='somepage.php?id=2'>Click here</a>

<?
if ($_GET['id']==2){
somefunction();
}else{
someotherfunction();
}

function somefunction()
{
//some code
}

?>

Thanks for the help.
The problem is, that I'm generating a list of such links (with a mysql query) and I don't want the user to see any data related information on the url.

So, might there be a function like the java 'onMouseClick' to do that?
