You can't call a method inside a class ,the only thing you can do is to call a php page
but you can call a php page that will call that method for you
ex :
function test() {
    var request = new XMLHttpRequest();
    request.open('GET', 'myfile.php', false);
    request.send();
    if (request.status === 200) {
      alert(request.responseText);
    }
}

Open in new window

myfile.php

<?php
include_once('myclass.php');
$obj = new myclass();
$obj->mymethod();
echo $obj
?>

Open in new window

The short answer is "yes, you can call a method."  But the longer and more articulate answer would be closer to what Moussa says.  You have to "call" a URL, which means to make an HTTP request.  The HTTP request can send parameters to the URL that you request.  These parameters can include the name of the class, the method, the arguments you want to send to the method, and any other information that is needed to complete the HTTP request.

Maybe if you can give us the details of why you want to do this, we can help with a sample implementation.  Is there any code you have tried yet?

greetings rgranlund, , You ask this question -
    "Can you use AJAX to call a Method inside of a class?"

I really can NOT understand what you may mean in your Question? ? ? ? ? ? ?

Can you please tell us about what you need to do for the web page DISPLAY result you want to have seen by the page user, , what data (as a database SELECT), , or what inputs in a page FORM do you have, and what is the Goal you need to end up with on the display page.
What operations do you think the AJAX http exchange needs to accomplish to get to your Goal?
