Answer 1

$var= $_POST[‘curp’]; // should be single quotes('curp') or double quotes("curp")

Your syntax here is incorrect because of the quotes, I don't know how you got that type of quote there, but that's not it. Single quote ( ' ) or double quotes( " ).

And you want to add the data returned to your #success div? Then use

$('#success').append(res); or $(res).appendTo('#success');

Hope that helps.
