title: Call multiple methods on object?
body: <p>I tried calling multiple functions on a single object. But I think I failed the syntax. Could you correct me please?</p>
  
  <pre><code>    $objMetaDaten-&gt;setStrTitle('test')
          -&gt;setStrBeschreibung('test')
          -&gt;setStrUeberschrift('test')
          -&gt;setStrCanonical('test')
          -&gt;setStrRobots(MetaDaten::INDEX);
  </code></pre>
