Example #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($rettrue));
  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());
?>

以上例程会输出:

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