@Epodax this posts asks "how it should be done", this is different from "how to do it with Ajax" — Adrien Brunelat, May 04 '16 at 12:42
@AdrienBrunelat I'm not sure I understand, SO is not a step-by-step / guide / tutorial service, so It's off-topic instead? — Epodax, May 04 '16 at 12:50
@Epodax I think it belongs to the uninteresting family of questions and should only be downvoted. There is no need for moderator intervention, it's an understandable question that can be answered and that is not a duplicate of another question. — Adrien Brunelat, May 04 '16 at 12:54
@AdrienBrunelat A question can be closed as off-topic without moderator attention (and most often is), this site is after all community driven. — Epodax, May 04 '16 at 12:55
@Epodax ok. Still, this question is "a practical, answerable problem that is unique to software development" so it's in the scoped defined in: http://stackoverflow.com/help/on-topic and is not off-topic — Adrien Brunelat, May 04 '16 at 13:01

If you use JQuery you can do it without your browser refreshing, an example:

Javascript

//execute in method

$.post("php file name.php",
    {
        name: "Foo",
        lastname: "Bar"
    },
    function(data, status){
        //after php has been this function is executed, data contains the data you send back from your php.
        alert(data);
    });

PHP

<?php
    //check if variables are send
    if(isset($_POST["name"]) && isset($_POST["lastname"])) {
        $name = $_POST["name"];
        $lastname = $_POST["lastname"];
        //do something with variabels
        echo "give back a result";
    }
?>
