title: Inconsistent behavior with die()
body: <p>Something that I think is really strange is happening when I use <a href="http://php.net/die" rel="nofollow"><code>die()</code></a>. The following code produces no output:</p>
  
  <pre><code>die($test);
  </code></pre>
  
  <p>However, the following code <strong>does</strong> output the integer value stored in $test:</p>
  
  <pre><code>die('test: ' . $test);
  </code></pre>
  
  <p>Why on earth would that be?</p>
