怎么扩展mySQLI_Result并添加新方法

原学程将引见若何扩大mySQLI_Result并添减新办法的处置办法，这篇学程是从其余处所瞅到的，而后减了1些海外法式员的疑问与解问，愿望能对于您有所赞助，佳了，上面开端进修吧。

成绩描写

Mysqli_Result类有fetch_all()办法以言数组(现实上是两维数组，由于言曾经是字段数组)的情势从成果散中1次前往多个言。别的，成果散具备以对于象情势前往单言的办法fetch_object()。

如今，我想扩大mysqli_Result类并添减新办法fetch_objects()(单数)，该办法将前往对于象的联系关系数组，个中联系关系键是记载ID[id=>Object()]。固然，为了前往扩大的成果散，我借须要扩大mysqli类并笼罩它的Query()办法。然则我没有晓得mysqli以及前往的mysqli_Result之间的衔接以及盘问参数是怎样传播的。

这应当是如许任务的：

$db=new ReallyMySQLi(...); //initiating my mysqli

$myrst=$db->query($SQL); //returned my extended result

//fetch_objects() returning associative array of objects
//with record ID as associative key
foreach($myrst->fetch_objects() as $id=>$object)
{
  echo 'Customer ID:'.$id; //or $object->id;
  echo 'Customer firstname:'.$object->firstname;
  echo 'Customer lastname:'.$object->lastname;
}

我在mysqli_result的推举谜底脚册中找到了这1面，并对于其停止了1些修补。不外我出有试过。

class Database_MySQLi extends MySQLi
{
 public function query($query)
 {
  $this->real_query($query);
  return new Database_MySQLi_Result($this);
 }
}

class Database_MySQLi_Result extends MySQLi_Result
{
 public function fetch_objects()
 {
  $rows = array();
  while($row = $this->fetch_object())
  {
$rows[$row->id] = $row;
  }
  return $rows;
 }
}

，用法为

$db=new Database_MySQLi(...); //initiating my mysqli

$myrst=$db->query($SQL); //returned my extended result

//fetch_objects() returning associative array of objects
//with record ID as associative key
foreach($myrst->fetch_objects() as $id=>$object)
{
  echo 'Customer ID:'.$id; //or $object->id;
  echo 'Customer firstname:'.$object->firstname;
  echo 'Customer lastname:'.$object->lastname;
}
