title: Call to undefined method PDO::bindParam()
body: <p>Can someone tell me why I am getting this error? Call to undefined method PDO::bindParam()</p>
  
  <p>Here is what I have, taken right off of PHPs site for stored procedures</p>
  
  <pre><code>$stmt = db::getInstance();
  $stmt-&gt;prepare("CALL delete(?)");
  $stmt-&gt;bindParam(2122, $return_value, PDO::PARAM_STR, 4000);
  $stmt-&gt;execute();
  print "procedure returned $return_value\n";
  </code></pre>
