Call to undefined method PDO::bindParam()
<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>
