update a variables value every 250 MS

Im busy on a website for a game. I'm currently at registration. Now the point is, that we want to let players put a code in their Ingame notes, so we can verify if a account really belongs to someone.

So I wrote a PHP class that can fetch the ingame notes. Now the one thing we still have to do, is set a javascript variable with these notes. So I can search through them for the code.

What I thought of, was to do a setInterval, and then in that function set the variable every 250 milliseconds. It appears to be a little harder then that. My first guess is that it has some scoping issue that makes the variable unavailable from outside that setInterval.

This is the JS I made:

var mission = "";
setInterval( function() { 
    var mission = "<?php echo Core\InGame::getNotes('TestPlayer');?>";
}, 250);
$("#mission").html(mission);

How is it possible that such a simple piece of code doesn't work?

I made a few things sure.

Is there a way to make this possible?

You cannot execute PHP code on the client side. The way to do this would be to call the php code with ajax or load()

myscipt.php

<?php echo Core\InGame::getNotes('TestPlayer');?>

myscript.js

setInterval( function() { 
    $("#mission").load('myscript.php');
}, 250);

Note, 250 ms is a very short interval and depending on network latency will not update every 250 ms. Try a larger interval.

You can move the whole code inside tgrget function;

setInterval( function() { 
    $("#mission").html("<?php echo Core\InGame::getNotes('TestPlayer');?>");
}, 250);

try 

var mission = "";
setInterval( function() { 
    mission = " some string ";
    $("#mission").html(mission);
}, 250);
$("#mission").html(mission);

You posted your PHP code.

This PHP, once interpreted and sent to the browser as HTML, gives something like this :

var mission = "";
setInterval( function() { 
    var mission = "Hello";
}, 250);
$("#mission").html(mission);

What is inside the setInterval won't change. It has been interpreted server-side, before being sent to the browser, and will always be "Hello". The PHP code disappears completely. So your interval works, but it sets always the same value...
