try alert(data.firstName.lastName);
EDIT:
I just tested this and it works as expected so cheers :)
<?php
$result['firstName']['lastName']='johan';
$data = json_encode($result);
echo $data;
?>
<html>
<body onload='myfunction(<?php echo $data; ?>);'>
<script>
function myfunction(data)
{
var fn = data.firstName;
alert(fn.lastName);// you can use data.firstName.lastName too
}
</script>
</body>
</html>

This should do it:
alert(data[fn].lastName);
Because your index is inside a variable, you have to use the brackets.

At least you need to eval your json string generated in php
In you alert use: data[fn].lastName

You can't access variable object property using dot notation. You need to use [] instead.
