Mappa is a simple object mapper for PDO.
$pdo->setAttribute(PDO::ATTR_STATEMENT_CLASS, [Mappa\Statement::class, [new Mappa\Hydrator()]]);
$stmt = $pdo->prepare("SELECT *, books.name || ' - ' || categories.name AS title FROM books JOIN categories ON categories.id = books.category_id WHERE books.id = ?");
echo get_class($stmt);
// Mappa\Statement
$stmt->execute([1]);
var_export($stmt->hydrate([Book::class, Category::class]));
// array (
// 'books' =>
// Book::__set_state(array(
// 'id' => '1',
// 'name' => 'B01',
// 'category_id' => '1',
// )),
// 'categories' =>
// Category::__set_state(array(
// 'id' => '1',
// 'name' => 'C01',
// )),
// '' =>
// stdClass::__set_state(array(
// 'title' => 'B01 - C01',
// )),
// )Mappa works with PHP 5.5 or later.
