PHP Question

How to call a php script/function on a html button click

Before someone has a go at me or marks this down, I have looked all over the internet to find out how to do this (including the same question on stackoverflow). I'm new, and I am finding it very hard to learn new concepts so please be easy on me.

What I want to do is call a php script/function on a button click. I have this running in WAMP if that helps. Here's my code:

<?php include 'the_script.php'; ?>

<button type="button" onclick="the_function()">Click Me</button>

the_script.php has this in it:

the_function() {
echo "You win";

Why isn't this working? I've heard about the button being client side etc. and PHP being server-side, which means that you cannot link the two together. I know that you have to use AJAX to make this work, however I legitimately have absolutely no clue how to do it. I've tried googling it etc., however I can't find anything. I know how to use AJAX and call events with it, however I still have no idea how to make it call a PHP script.

Can you please make your answers as clear and simple as possible, I'm new to this

Thanks for the help :)

EDIT ***

For some reason wherever I go everyone's code is different. The way I have been taught AJAX looks completely different. Can you please write it this way so I can understand? Thanks, here's an example:

var request;

if (window.XMLHttpRequest) {
request = new XMLHttpRequest();
} else {
request = new ActiveXObject("Microsoft.XMLHTTP");

request.open('GET', 'file.php', true);

request.onreadystatechange = function() {

if (request.readyState===4 && request.status===200) {
do stuff



Just try this:

<button type="button">Click Me</button>
<script type="text/javascript">

                type: 'POST',
                url: 'script.php',
                success: function(data) {


In script.php

  echo "You win";
