Check out PHP's exec() command.

string exec ( string $command [, array &$output [, int &$return_var ]] )

It allows you to issue commands to the shell (such as a call to a Java program, etc.) and return results back to PHP.

Just give you an idea

compile and build your JAVA program, and your program should accept command line arguments as input and write output to STDOUT (i.e. write to System.out using System.out.print and such.)
Then, in PHP, use exec() to execute that jar file.

I think you mean `System.out`. Java != C. Still +1 – 11684 Dec 16 '12 at 13:50
I somehow assume that the OA knows output to STDOUT here means `System.out` >. – luiges90 Dec 16 '12 at 13:50
Yeah, but that you and I do know that doesn't necessarily mean every beginning or amateur programmer who reads this knows that. – 11684 Dec 16 '12 at 13:52
Anyway, just fixed up the answer. :) – luiges90 Dec 16 '12 at 13:53
Noticed that. But you have my upvote already. – 11684 Dec 16 '12 at 13:54

Disclaimer: I assume you mean that you want to connect a PHP or Java Website to a PHP or Java Server.

Usually when to alien systems have to communicate to each other in a web context - "webservices" come in play. There you can use a SSL encrypted connection to send and receive messages/data.

The two Buzzwords you can investigate reading are REST and SOAP.
