Beispiel #1 MysqlndUhConnection::queryReadResultsetHeader() example

<?php
class proxy extends MysqlndUhConnection {
 public function queryReadResultsetHeader($res, $stmt) {
  printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
  $ret = parent::queryReadResultsetHeader($res, $stmt);
  printf("%s returns %s\n", __METHOD__, var_export($ret, true));
  return $ret;
 }
}
mysqlnd_uh_set_connection_proxy(new proxy());

$mysqli = new mysqli("localhost", "root", "", "test");
$res = $mysqli->query("SELECT 'Welcome mysqlnd_uh!' FROM DUAL");
var_dump($res->fetch_assoc());
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

proxy::queryReadResultsetHeader(array (
  0 => NULL,
  1 => NULL,
))
proxy::queryReadResultsetHeader returns true
array(1) {
  ["Welcome mysqlnd_uh!"]=>
  string(19) "Welcome mysqlnd_uh!"
}
