UPD Предложение от Башка:

<?php 
class MyMysqli extends mysqli{ 
  public function myQuery($query, $params){ 
    $stmt = $this->prepare($query); 
    $p = array_values($params); 
    array_unshift($p, array_keys($params)); 
    call_user_func_array([$stmt, 'bind_param'], $p); 
    $result = $stmt->execute(); 
    $stmt->close(); 
    return $result; 
  } 
}                                                              
$mysql = new MyMysqli("localhost", "my_user", "my_password", "world"); 
$mysql->myQuery('SELECT * FROM users WHERE login = ?', ['s' => 'admin']);
