title: Binding parameters with MySQLi throws "undefined method" error?
body: <p>I have this code:</p>
  
  <pre><code>$dateInt = intval($date);
  $stmt = $this-&gt;db-&gt;prepare('SELECT * FROM establecimientos WHERE timestamp &gt; ?');
  $stmt-&gt;bindParam($dateInt);
  $stmt-&gt;execute();
  </code></pre>
  
  <p>And I'm receiving this error:</p>
  
  <blockquote>
    <p>Call to undefined method mysqli_stmt::bindParam()</p>
  </blockquote>
  
  <p>I'm sure there's something terribly wrong, but I cannot certainly know!</p>
