Answer 1

You would create a file that looks like this

// update_session.php

<?php session_start(); 
if (isset($_POST["val"])){
       $_SESSION["val"] = $_POST["val"];
}

Then for your html you would have (note I changed attribute to a data-value because value is not a valid attribute for li whereas the data- prefix attributes are valid.)

<ul id ='my_ul'>
<li data-value="123">123</li>
<li data-value="456">456</li>
</ul>

And you jquery (in a document ready block) would look like this.

$('#my_ul').on("click", "li", function(){
   $.ajax("update_session.php",{method:"post", data:{val:$(this).attr("data-value")}}); 
});
