title: PHP and Java, how to join them?
body: <p>I'm learning Java programming now, and I wanna use Java classes that I created in my PHP systems. Every tutorial what I found is too old and the links doesn't exist anymore. I tried to use "apt-cache search php-java" in my terminal but no results came (I think this just works for repositories, am I right?).
  Does someone have any help?
  I use Ubuntu 15.04, php5.6.4, java 1.7.0_85 and my system is 64bits.
  Thanks for the help :)</p>
