  <p>As described <a href="https://tokbox.com/opentok/libraries/server/php/" rel="nofollow">here</a>, It says 'Composer' needs to be there to install the SDK. I want to know if is there any different method though which we can just load required classes and run the application? OpenTok is really new to me.</p>
  
  <p>Any help is appreciated.</p>
