通过JQuery ajax执行PHP函数

I know it is not possible to simply call a function through ajax. As it only sends data via HTTP headers. However, I am trying to achieve something. I'm trying to execute a piece of PHP code, by the click of a button. The code consists of a shell_exec("omxplayer file.mp3") So my ultimate goal is, to have a page load, display a button, which in turn, once clicked, will execute this piece of code (shell command).

I have looked for solutions and have not found one, even though there have been a lot of questions asked with a similar title to mine.

How can I achieve this concept?

EDIT: My ultimate goal is to use the shell_exec() to start playing a file using omxplayer on a linux machine.

    You can use .get()

    <!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script>
$(document).ready(function() {
    $("button").click(function() {
        $.get("script.php?code=myFunction", function(data, status) {
            alert("Data: " + data + "
Status: " + status);
        });
    });
});
</script>
</head>
<body>
    <button>Execute Command</button>
</body>
</html>

    script.php

    if (!empty($_GET['code']) {
    $output = shell_exec(<do shell command here>):
    echo $output;
}
