You need to separate the code in Controller, View and Model:
Model for DDBB operations.
Controller: control where the data goes and how it can be displayed, and other logic.
View, here is where the form is rendered.
Codeigniter has a great documentation to learn how to do it.
Models has the same url, but for models, i've not reputation enough to post 3 links, sorry

You can do like this
$(document).on("change","#select",function(){
$.ajax({
url:""// path to your controller function. here keep all the code which is present in your getuser.php in to a function in controller
data:{"key":value,"key":value}
dataType:"HTML",
success:function(data){
$("#txtHint").html(data)// this you can do 2 things, either manipulate all your data in controller
//and directly change the html of the div, or u can get the required data
}
})
});
