extract($str) is what you're looking for. Takes an array and breaks it up into individual variables using the keys of the array as the variable names. http://php.net/manual/en/function.extract.php

You send the request to the script that ajax would normally be submitting the login info to. It doesn't need to be an "ajax" request, unless they are specifically looking for the XMLHttpRequest header in which case you'd just need to add it to the CURL header to simulate an ajax request. Something like: curl_setopt($ch, CURLOPT_HTTPHEADER, array("X-Requested-With: XMLHttpRequest", "Content-Type: application/json; charset=utf-8"));

Isn't what you are calling internal the same as private? Try calling a private method from outside the class.
