//the form, the page will die.
//Using die isn't a very good practice, you may want to look into
//displaying an error message within the form instead.
//We could also do front-end form validation from within our Android App,
//but it is good to have a have the back-end code do a double check.

//app will parse

//already a user with the username specificed in the form. ":user" is just
//a blank variable that we will change before we execute the query. We
//do it this way to increase security, and defend against sql injections
$query = " SELECT 1 FROM users WHERE username = :user";
//now lets update what :user should be
$query_params = array(
':user' => $_POST['username']

//Now let's make run the query:
try {
// These two statements run the query against your database table.

$result = $stmt->execute($query_params);
}
catch (PDOException $ex) {

//or just use this use this one:

die(json_encode($response));
}

//If we have made it this far without dying, we have successfully added
//a new user to our database. We could do a few things here, such as
//redirect to the login page. Instead we are going to echo out some
//json data that will be read by the Android application, which will login
//the user (or redirect to a different activity, I'm not sure yet..)
