this is my code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>
<a href="one.php?function=yes">click me</a>

<body>
<?php
if( isset($_REQUEST['function']) )
{

function my()
{
echo "hello";
}

}
?>

</body>
</html>

when i click on the link the url changes to

http://example.com/serendibart/one.php?function=yes

but

I dont see the message 'hello' displayed.

why is it not working?

The function isn't being started, to start the function do my(); or take it out of the function and it will echo hello.
<?php
if(isset($_REQUEST['function']))
{
echo "hello";
}
?>

{

function my()
{
echo "hello";
}

Ok, first I have to ask why you are trying to define a function inside an if statement.
