许久不练，要写起来。

hello('PHP'); echo "
"; class TheClass {} interface TheInterface {} trait TheTrait {} $object = new class('A', 'B', 'C') extends TheClass implements TheInterface { use TheTrait; public $A; private $B; protected $C; public function \_\_construct($A, $B, $C) { $this->A = $A; $this->B = $B; $this->C = $C; } }; var\_dump($object); echo "
"; echo get\_class($object); echo "
"; class Outer { private $prop = 1; protected $prop2 = 2; protected function outerFunc1() { return 3; } public function outerFunc2() { return new class($this->prop) extends Outer { private $prop3; public function \_\_construct($prop) { $this->prop3 = $prop; } public function innnerFunc1() { return $this->prop2 + $this->prop3 + $this->outerFunc1(); } }; } } echo (new Outer)->outerFunc2()->innnerFunc1(); echo "
"; echo get\_class(new Outer); ?>

输出：
