Phil,
You don't do it the same way in PHP. Java is much more event-driven
than PHP; it's doing some things behind the scenes that PHP doesn't do
for you.
When the submit button is pressed, a form is submitted to the server.
This includes a request for the page identified in the action= parameter
of your <form> element.
Java will take this request and drive the appropriate listeners for you.
PHP won't. In PHP you get the input via either $_GET or $_POST
(depending on the method= parameter) and handle the request.
It's a little more work for you to do it - but less overhead on the
server (Java calls action listeners for every bean being used, whether
you've overridden it or not).
