title: PHP: file_get_contents(compress.zlib://php://input): failed to open stream: operation failed
body: <p>After upgrading to PHP5.6 the following doesn't work anymore:</p>
  
  <pre><code>$json = file_get_contents('compress.zlib://php://input');
  </code></pre>
  
  <p>For this line I get the following error message: </p>
  
  <blockquote>
    <p>file_get_contents(compress.zlib://php://input): failed to open stream: operation failed</p>
  </blockquote>
  
  <p>What is wrong here? I need to decompress the received content, because my client sends a gzip compressed content to the server. A ssl connection is used, but shouldn't be a problem, because the http server (lighttpd) should already decrypt the content (at least it was working in a previous version).</p>
  
  <p>Any ideas?</p>
