     }  
if (isset($_GET['id']))

        echo "HELLO";
     }

Answer 1

When a click occurs, the Javascript handler will be fired, then the browser will load the page specified in the href attribute.

If you wish to execute some Javascript before the redirection happens, continue using your onclick event:

<a href="index.php?id=1" onclick="doSomethingInJavascript()">...

Your Javascript function can return false if you wish to cancel the redirection to the PHP page, if necessary.

Also be aware that AJAX calls will allow you to call a PHP script and perform other Javascript functionality, all without loading a new page.
