how to access javascript variable with php using ajax

Hi, I am trying to figure out how to access a javascript variable with php, in order to then store the variable in a database. This is what I've tried. I was hoping that in my ajax.php file it would display $my_variable, but it doesn't.

Here is my javascript:

var $my_variable = "something";
$.ajax({
     url: 'ajax.php',
     data: {x: $my_variable},
     type: 'POST'
});

And here is ajax.php:

<?php echo $_POST['x']; ?>

What am I doing wrong please? How can I get my php file to display my javascript variable?

This post is really old and I use Laravel and Angular now so I do it differently to before, so sorry, I'm not sure exactly what I did back then. But if you post your code perhaps I can help...
