The best way is to use JSON as the dataType.
In PHP, all you need to use is the json_encode() function to convert a
PHP array to JSON. It's like an easy way to pass back an array full of
data back to the client that you can manipulate as regular Javascript
variables.
For example, your PHP code would look like:
$myArray = array(
'firstName' => 'John',
'lastName' => 'Doe',
'error' => 0
);
echo json_encode($myArray); // echo your response back
exit;
Then in your $.ajax success callback function:
function(data) {
alert(data.firstName); // -> alerts 'John'
}
