Send variable to PHP script while getting data

Question

First of all let me tell you all I'm very new to js, jQuery & ajax. But I'm very well with PHP.

I got a jQuery script from the internet:

function getMessages (){
        $.get('php/chatGetter.php', function(data){
            $("#msgbox").html(data);
        });
    }

    setInterval(function(){
        getMessages();
    }, 500);
});

As you can see it gets data from chatGetter.php page and shows in div whose id is msgbox every 500 millisecond.

I want to send a php variable ($abc ="something";) through function getMessages to chatGetter.php page every time the getMessages function is executed. But I'm not getting how to do that.

Make these changes in your jQuery code:

function getMessages (){
        var something = 'something';
        $.get('php/chatGetter.php?abc=' + something, function(data){
            $("#msgbox").html(data);
        });
    }

 setInterval(function(){  
      getMessages();
 }, 500);

And then, in the chatGetter.php file, add this on the top:

if(isset($_GET['abc'])) {
     // do whatever you wanna do, here...
}

Here's the working example: http://jsfiddle.net/mnL5Lsmz/

If your JS code is in your PHP file do this.

function getMessages (someVariable){
        $.get('php/chatGetter.php?abc=' + someVariable, function(data){
            $("#msgbox").html(data);
        });
    }

    setInterval(function(){
      var someVariable = '<?php echo($abc);?>';  
      getMessages(someVariable);
    }, 500);
});
