Assign js variable value to php variable

I have declared a javascript variable ,

 var myJavascriptVar = 12345;

And unable to assign that value to php variable;

 $myPhpVar = 'myJavascriptVar'; 

I know Ajax may be the solution of my problem. But i don't know how to use Ajax and solve the problem.

Using Cookie is the better solution i think -

Try using ajax with jQuery.post() if you want a more dynamic assignment of variables.

The reason you can't assign a variable directly is because they are processed in different places.

It's like trying to add eggs to an already baked cake, instead you should send the egg to the bakery to get a new cake with the new eggs. That's what jQuery's post is made for.

Alert the results from requesting test.php with an additional payload of data (HTML or XML, depending on what was returned).

$.post( "test.php", { name: "John", time: "2pm" })
  .done(function( data ) {
    alert( "Data Loaded: " + data );
  });

I have a better solution: Here, in the .php file, I have a variable called javascriptVar. Now, I want to assign the value of javascriptVar to my php variable called phpVar. I do this by simply call javascript variable by document.writeln in the script tag.

    
                var javascriptVar = 'success';
             ";
        
    
        $phpVar = "";
    ?>

PHP is server side language and JS is client side.best way to do this is create a cookie using javascript and then read that cookie in PHP

I guess you can use cookies for it.

1) First add a cookie jquery plugin.

2) Then store that window width in a cookie variable.

3) Access your cookie in PHP like $_COOKIE['variable name'].

Javascript will be interpreted in Client's browser and you can not assign it to PHP variable which is interpreted on SERVER .

Feasible Solution : You can submit the Javascript value via ajax or through form submit.
