jQuery and Php variable calling

Question

I have a problem with jQuery and PHP.

I have a .php file that contains a variable, for example var surname = ""; The problem that I am facing is, I want remotely access it from a .html file and give it a value from another variable in the .html file.

Is there any way to do it?

Thanks.

Ok, so you said you wanted to get a variable from HTML and send it to the PHP file to change data, that is what the variable 'varfromhtml' is. You just need to give it a value you want to send, you can get the value of a div using jQuery eg

<div id="div">data</div>
var varfromhtml = $.("#div").val();

The variable 'varfromhtml' is now equal to 'h08sahdas', you can mess around with that to get it right for you.

Here is the final script:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
var varfromhtml = $.("#div").val();

$(document).ready(function(){
$.ajax({
    method: "POST",
    action: "myfile.php",
    data: {
        varfromhtml:varfromhtml
    },
    success: function(data){
        $('#mydiv').val(data);
    }
});    
</script>

You should explain how this works using comments. They may not have prior experience with Ajax.
