title: Is a local PHP include() file cached?
body: <p>After doing some research i'm struggling to find a definitive answer on how and if a PHP <code>include()</code> file is cached.</p>
  
  <p>The closest i've found is <a href="http://forums.devshed.com/php-development-5/php-cache-includes-61074.html" rel="nofollow noreferrer">here</a> but it doesn't quite make sense to me.</p>
  
  <p>I have several methods that use other methods from different files and I want to avoid placing include()'s just at the top of the file but i'm not sure how this might affect performance.</p>
  
  <p>Any help is appreciated.</p>
