title: use word printout in PHP
body: <p>I'm using PHP COM to manipulate msword.</p>
  <pre><code>$word-&gt;PrintOut(false, empty, empty, empty, empty,....);
  </code></pre>
  <p>Some parameters/varables are &quot;optional&quot;, but can't be set as null or &quot;&quot; or 0</p>
  <p>Will throw error: <strong>Parameter 16: Type not match</strong> (translated)</p>
  <p>I found someone using &quot;<strong>System.Reflection.Missing.Value</strong>&quot;  in <strong>C#</strong>   (&quot;empty/not set&quot;)</p>
  <p>but, how can I use this in PHP? or something simillar.</p>
  <p>thanks</p>
  <p>I want to use <strong>PrintOut</strong> in php with parameters.</p>
