Actually, the callbackKey option is so you can specify what the GET variable
the callback should be sent as.
callbackKey: 'foo' would set a request of
myurl.com/?foo=Request.JSONP.request_map.request_0, or something similar. So
in your PHP, you need to check the same $_GET variable.
<?php
echo $_GET['foo'] . '(' . $the_json . ')';
?>
Leaving callbackKey to it's default, callback, is usually the desired
result. Then you could look for $_GET['foo'].
