How to echo a JS-variable in php and then append or include php file to HTML object?

Question

Hi stackoverflow people,

I'm making a variable code where you can easily put another file-code in between e.g. a div. I'm wondering if you can include a PHP-file via JavaScript, with JS variables. I can do it via PHP but can I include a file with JS?

HTML:

<div id="someId">THE INCLUDE HERE</div>

JS:

var tag_id = 'someId'; //comes form DB
var url = 'data/includes/code.php'; // comes from DB

$('#' + tag_id).html('<?php include("' + url + '"); ?>');

As you can see, tag_id is the id of a object and the url is not static but comes from the DB.

I've read and tried those (but didn't work..):

Maybe I have to think out of my box, can you guys help me?

(Sorry for bad English...)

just so you know, this won't work because php is executed before javascript runs, and php won't run again until the next page load. — iam-decoder, Jul 27 '15 at 18:00
you can use AJAX to get the html output of a page and display that, but you wont be able to include php variables from that file into your current file. — iam-decoder, Jul 27 '15 at 18:02
Wait, i've found something else: `$('#' + tag_id).load(url)` , this works! — Dirk Jan, Jul 27 '15 at 18:04
`$('#' + tag_id).load(url)` is a form of ajax which is why it works — developerwjk, Jul 27 '15 at 18:05

No you cant include a php page through a JS variable, however you could use AJAX to retrieve the HTML contents and place it in a DOM like so:

$.ajax({
    type: "GET",
    url : "data/includes/code.php",
    success: function(result) {
        $('#' + tag_id).html(result);
    }
});

This can be simplified to:

$('#' + tag_id).load(url);
