1.Trait is a code reuse mechanism prepared for single inheritance languages like PHP. Traits are designed to reduce the limitations of single-inheritance languages and allow developers to freely reuse methods in independent classes within different hierarchies.
2. Members inherited from the base class will be overridden by members inserted by the trait.
3. Code example:
trait T{ public function run() { parent::run(); echo 'Trait:'.__CLASS__.'<br>'; }}class P{ public function run() { echo 'Class:'.__CLASS__.'<br>'; }} class C extends P{ use T;}$c = new C();$c->run(); //输出结果 //Class:P //Trait:C
