How to put the ajax response/result into variable php

Question

Can I put the ajax response into variable? So that I can echo the variable into php?

ajax.php

<script>
function random_no(){
    $.ajax({
        url: "test.php",
        success: function(result){
            $("#random_no_container").html(result);//the result was displayed on this div
        }
    });
}
</script>

On my sample code above, i call the query result from test.php and the result was displayed on the div but i want to put that on the variable and echo the variable. something like the code below

<?php echo $variable;?>

Can this possible? please help me. Thank you so much.

Answer 1

You can't PHP is executed on server and Ajax from the client so you cannot assign PHP variable an ajax response. Once a PHP is rendered on the client side it is just HTML no PHP code.

Answer 2

    function random_no(){
        $.ajax({
            url: "test.php",
            success: function(result){
               var result_val=result;
               alert(result);            
            }
        });
    }

As @dev answered , you need to execute server and client code differently ! I answered here for your need variable only .But in developing website, should not use javascript in php tag <?php ?>

ajax.php

<div id="random_no_container">
    <?php
     if(isset($_GET['variable'])) {
        $variable = $_GET['variable'];
        echo $variable;
     } else {
        echo "<script>sessionStorage.setItem('stopped',0);</script>";
     }
     ?>
</div>
<script>
var stopped = sessionStorage.getItem("stopped");
if(stopped == 0) {
    random_no();
}
function random_no(){
    $.ajax({
        url: "test.php",
        success: function(result){
            sessionStorage.setItem("stopped",1);
            //$("#random_no_container").html(result);//the result was displayed on this div
            location.href = "ajax.php?variable="+result;
        }
    });
}
</script>
