title: Printing a variable in PHP does not work
body: <p>I've got this piece of code:</p>
  
  <pre><code>&lt;?php
    $userid = $me['id'];
    function showifuserexists() {
  ?&gt;
  &lt;html&gt;
    &lt;head&gt;&lt;/head&gt;
  &lt;body&gt;
    &lt;a href="file.php?element1=aaa&amp;userid=&lt;?php print $userid; ?&gt;"&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  &lt;?php
  } 
  ?&gt;
  </code></pre>
  
  <p>For some reason I can't get the php <code>$userid</code> to show up in the html link. I've tried <code>echo</code> too. Help?</p>
