title: PHP: set_include_path and require_once(): Failed opening required
body: <p>I got a problem with my php settings, I know that for sure 'cause the exact same lib works perfectly for my partner at HIS server.</p>
  
  <pre><code>$inc_path = get_include_path();
  $inc_path .= PATH_SEPARATOR . "./rtmp" . PATH_SEPARATOR . "./SabreAMF";
  set_include_path($inc_path);
  
  require_once 'rtmp/SabreAMF/OutputStream.php';
  require_once 'rtmp/SabreAMF/InputStream.php';
  require_once 'rtmp/SabreAMF/AMF0/Serializer.php';
  require_once 'rtmp/SabreAMF/AMF0/Deserializer.php';
  require_once 'rtmp/SabreAMF/TypedObject.php';
  </code></pre>
  
  <p>and this is what I get</p>
  
  <pre><code>Warning: require_once(rtmp/SabreAMF/OutputStream.php): failed to open stream: No such file or directory in C:\Program Files (x86)\EasyPHP-12.1\www\phpLoL-master\rtmp\RtmpClient.php on line 7
