Hi, everyone

I searched a lot but couldn't find it

var HTTP=new XMLHttpRequest();
var params={name:"jack",family:"jackers",age:"30"};

HTTP.open("POST","http://127.0.0.1/test/test.php");
HTTP.send(params);

</script>




<?php

//file test.php
if (isset($_POST['name'])){
    print_r($_POST['name']."<br>");
    print_r($_POST['family']."<br>");
    print_r($_POST['age']);

}

?>

I think this would help you to get more specific regarding the question..

<script>
 function sayHello() {
   var v1 = "hello";
   var v2 = "everyone";
   window.location.href = "result.php?w1=" + v1 + "&w2=" + v2;
 }
</script>

result.php

function sayHelloBack() {
   if (isset($_GET["w1"]) && isset($_GET["w2"])) {
     $hello = $_GET["w1"] . " " . $_GET["w2"];
     echo $hello;
   }
}
