How can i in JavaScript run php script without returning a value ?
I need run for sample this php script

echo '<table><tr><td>' .$a.'</td></tr></table>';

Javascript is run in the browser. PHP is run on the server and sends a response back to the browser. You can run a server with PHP installed on your local machine.
