title: phpinfo() not working in apache2
body: <p>I wanted to install <code>php5.3</code> on <code>ubuntu 14.04</code>(its not natively available as ubuntu pkg), so I installed each <code>apache2</code>, <code>mysql5.6</code> and <code>php5.3</code> separately.</p>
  
  <p>PHP5.3 is utmost important for my project.</p>
  
  <p>Now i wanted to test if each of them was working fine together.</p>
  
  <p>I created a info.php file in <code>/var/www/html/</code> containing code as <code>&lt;?php phpinfo(); ?&gt;</code> but the output showed an output like an HTML rendered page.</p>

  <p>Can anyone please tell me how to test/check if all three of them are working together fine?</p>
  
  <p>I would be very thankful, if anyone can please give a link or detailed-description where I can read instructions on how to integrate all three of them together while not uninstalling any of them.</p>
