I wanted to know if you can design a method for a JAVA applet to send data to
a PHP server and vice versa (PHP server sends data to the JAVA applet) on the internet, so that either program does something different based on what the data is?
Thanks

Not really helpful, but you really can design any sort of Java or php
program to do anything you want. The question is why? Is there some
application you don't have access to that's written in Java.
Web-based applications have two ways to send data to each other--GET
with arguments and POST with embedded arguments.
If you have some separate client/server thing going, then it's an
interprocess communications thing over a network socket. Use whatever
way to code that you know how. Php has socket functions as I'm sure
Java does. You just need to come up with a protocol and design that.

Not sure of what you mean with "together", given that Java applets run
on top of a browser and PHP scripts typically run on top of a web server
(never a browser) but short answer is "yes, you can". But it's important
to understand that the way HTTP is designed makes it impossible to
*start* a connection from the server. If you need to communicate with
the browser, you must start the connection from Java.

Your question is framed in such a way that I get the impression you are
not sure what (Java applet/PHP) runs where.
"so that either program does something different based on what the data
is" <-- that is vague.
To clarify:
An applet runs in the browser (client).
An applet can request ANY data from ANY server. If you use the same
domain where the applet is hosted, things will be easier to set up for you.
So if your applet is hosted here:
http://www.example.com/yourpage.php
and the HTML coming from there embeds an applet, that applet can easily
reach to www.example.com, but not to www.anotherexample.com.
It needs additional rights for that (possibly this includes 'signing'
the applet.)
Ask in a java newsgroup for details. It has been years ago since I
programmed Applet <--> PHP communication, so better ask the experts.
And PHP ALWAYS runs on the server. It will never run at the client
(browser). PHP produces the HTML (or images, or whatever) that is sent
to the browser.
So as far as the browser is concerned, it could all be static HTML as well.
Hope this helps you approaching your puzzle. :-)

A php process on a server will process whatever requests are passed to it.
You will need to make the java applet send suitable requests (probably
using http get or post protocols), design your php process to process
those requests and return relevant data, and then have your java applet
process the responses and do stuff accordingly.
You might want to make the content of your responses some form of xml,
json, plain text, or some serialised or ascii encoded data format, rather
than a web page. This might involve using php functions to ensure that
the web server under which the php process is operating sends the data
with the right http protocol headers.
