title: PHP heredoc not retaining format
body: <p>Using the following code I expect to see 5 separate lines displayed. Instead it wraps everything together on one line... no tabs, no leading spaces, no blank line. Not what I was expecting.</p>
  
  <p>After viewing other code, the programmer inserted a series of 's which I tried (using <br /> instead) and got some of the results I was looking for. Am I expecting too much? I never could get leading spaces and tabs to work. Could this be a setup problem?</p>
  
  <pre><code>&lt;?php
  $author = "Alfred E Newman";
  
  $out = &lt;&lt;&lt;_END
         This is a Headline
  
     This is the first line.
     This is the second.
        - Written by $author.
  _END;
  
  print $out;
  // echo $out; // ... didn't format as expected either
  ?&gt;
  </code></pre>
