how to get value of myjsvar into php variable $myphpvar?

You can't use javascript variable in php code. Php code run's on the serverside and javascript code runs in the client side. You can't ask the browser to run php code.
Your variable loc will have a value only when the code reaches the browser.
If you want to get some value from server and combine it with javascript variables then do the following.
Use an ajax request and send the desired values to server. The server will return with a response. Use that response text and store it in your action variable.

1. <script>
2. document.getElementById('description').innerHTML = description;
3. </script>
4. <div id="description"></div>
How to get the value of line 4 into PHP code?. Also when I use the traditional way
<?php $weather = <div id = "description"></div>?>
The weather variable is not displayed wherever I want it to be displayed.
Any help is greatly appreciated. Thank You.
The PHP is processed on the server side, while the Javascript value is processed in the user's browser. So when the page is sent, there is no value there yet.
You can do this:
<?php
$weather = '<div id="description">Details go here</div>'; // define variable
echo $weather; // include / print variable
?>
But if the value does not exist yet that you want to include, then you need to use AJAX to send it to PHP if that's indeed what you need. Although if it doesn't need to go back to the server, it can likely be done just with JavaScript on the client side.
I suggest finding some good books on learning PHP / learning JavasScript / learning HTML.

Is there a way to get the jquery this.val() read into PHP at runtime?
I have a dynamic push of data and need to run a SQL statement that depends on the jquery value of this.val() - so something like
<?php $sql = "select * from table where id = " . this.val(); ?>
No, becouse PHP can't read user's DOM.
You need to make an ajax request to send the data to the server.
jquery.ajax

I would like to echo some php code in javascript for certain reasons but the code does not get executed, when i use the code inspector i notice that the php code has been commented out.
This is the code:
var code = '<?php echo time_passed(strtotime(' + new Date().toLocaleString() + ')); ?>';
$('#page').html(code);
basically i am passing the javascript datetime value to a php function which should then echo the results into the code variable.
I then output the value of code to a container with an id of page.
PHP is on the server end. In the manner your using, there is no way to for PHP and JavaScript code execution to interact. You would need to user AJAX to communicate between front end execution (JavaScript) and back end execution (PHP).

I would like to pass a text string to a php file,
Here is my code:
var t2 = new Text(figure_defaultFigureTextStr, x, y + figure_defaultFigureRadiusSize/2,
figure_defaultFigureTextFont, figure_defaultFigureTextSize);
t2.style.fillStyle = figure_defaultFillTextStyle;
f.addPrimitive(t2);
Basically PHP is a server side language, you cannot execute it client-side.
So the best bid would be, to send a HttpPost request alongwith the variable value. This would send the data to the server. There you can save the data of it inside a file or what so ever.

</html>
any help must be appreciated..Thnks
you can use php variables to javascript but not javascript variables to php.. because javascript executes on client side and php executes on server side.. so php is executed before javascript gets executed..
So simply you cant...
the only thing you can do this by using ajax....
