Anonymous fields for PHP trait and go struct

first of all, the concept of trait in PHP is the concept of struct anonymous field in the Go language. is the desire to incorporate one structure into another, adding functionality to another structure. Rather than through tree-shaped inheritance PHP Trait Demo

<?php

    class Base {public
        function SayHello () {
            echo ' Hello ';
        }
    }

    Trait SayHello {public
        function SayHello () {
            Parent::sayhello ();
            echo ' World! ';
        }

        Public Function Sayhi () {
            echo ' sayhi ';
        }
    }

    Class Myhelloworld extends Base {use
        sayhello;
    }


    $helloWorld = new Myhelloworld ();

    $helloWorld->sayhello ();
    $helloWorld->sayhi ();
# #输出结果
Hello World!sayhi
# #说明用trait定义的结构可以增强其他结构的功能
