title: Can PHP Traits be disabled in 5.4.x?
body: <p>I have a client using Rackspace Cloud Sites which advertise PHP 5.4 on their platform but I have been advised via their online support that traits cannot be used.</p>
  
  <p>When using traits I receive a 500 error and finding no issue with the code I asked their online support to be told "it is not allowed in our environment". Using the basic PHP example code below results in a 500 Internal Server Error:</p>
  
  <pre><code>class Base {
      public function sayHello() {
          echo 'Hello ';
      }
  }
  
  trait SayWorld {
      public function sayHello() {
          parent::sayHello();
          echo 'World!';
      }
  }
  
  class MyHelloWorld extends Base {
      use SayWorld;
  }
  
  $o = new MyHelloWorld();
  $o-&gt;sayHello();
  </code></pre>
  
  <p>Is there some reason why Traits would be disabled or can they even be disabled? The version reported by phpinfo() is 5.4.10.</p>
