title: Good combination of web application languages
body: <p>I've looked around some of the asked questions and I noticed many questions dealing with THE best web application language. I'm curious into looking into a combination of web application languages, possibly some that would compliment each other well. At the moment my list of possible web app languages at the moment are:</p>
  
  <ul>
  <li>PHP</li>
  <li>Ruby on Rails</li>
  <li>JavaScript</li>
  <li>AJAX (not really a language on its own)</li>
  <li>Grails</li>
  </ul>
  
  <p>I know that certain ones like JavaScript and AJAX work well together but I'm curious about the rest. What about PHP and JavaScript? Does Rails play well with others? Is looking to use a combination of languages even a possibility? I know that some may be used for different kinds of applications but I would like to focus on more than just 1 of them. Thanks for the help. Any and all comments are appreciated. </p>
