Can any one tell me how to write JavaScript code inside the php code ?

Answer 1

JavaScript code can't be written inside <?php ?> element. So, close that element (i.e. add the end tag ?>) at first. Then add <script> element and write JavaScript code inside it.
Edit: JavaScript code can be embedded inside <?php ?>. Check @WASP's answer.
