<?php
class stmt_proxy extends MysqlndUhPreparedStatement {
 public function prepare($res, $query) {
  printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
  $query = "SELECT 'No more you-know-what-I-mean for lunch, please' AS _msg FROM DUAL";
  $ret = parent::prepare($res, $query);
  printf("%s returns %s\n", __METHOD__, var_export($ret, true));
  var_dump($ret);
  return $ret;
 }
}
mysqlnd_uh_set_statement_proxy(new stmt_proxy());

$mysqli = new mysqli("localhost", "root", "", "test");
$stmt = $mysqli->prepare("SELECT 'Labskaus' AS _msg FROM DUAL");
$stmt->execute();
$msg = NULL;
$stmt->bind_result($msg);
$stmt->fetch();
var_dump($msg);
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

stmt_proxy::prepare(array (
  0 => NULL,
  1 => 'SELECT \'Labskaus\' AS _msg FROM DUAL',
))
stmt_proxy::prepare returns true
bool(true)
string(46) "No more you-know-what-I-mean for lunch, please"
