Use the jQuery.getJSON method instead of .get , if you want your JSON to be parsed. Also, make sure that the jQuery library is correctly loaded.
function clickHere(){
$.getJSON("index.php", function(data) {
alert(data.user);
});
}
Currently, you're using $.get(url, function(data){...}) . In this context, data is a string containing the response from the server:
{"user":"Robin098","id":"80465"}
Using alert(data) inside the function will show this string.

It looks like you're setting up $returnThis , but then returning $aReturn . Don't you want:
$returnThis['user'] = "Robin098";
$returnThis['id'] = "08465";
echo json_encode($returnThis);
