PHP抽象类和PHP接口

1.抽象类

<?php
    abstract class a{
        public $name;
        public function __construct($name){
            $this -> name = $name;
        }
        public function af(){
            echo $this -> name;
        }
        abstract public function aff();
    }
    class b extends a{
        public function aff(){
            echo $this -> name;
        }
    }
    $a = new b('欧阳');
    $a -> af();
    echo '<br>';
    $a = aff();

2.接口类

<?php
  abstract class P{
      protected $name;
      protected function __construct($name='peter'){
          $this->name;
      }
      public function getName(){
          return $this->name;
      }
      abstract protected function setName($value);
  }
  class stu extends P{
      public function __construct($name = 'peter'){
          parent::__construct($name);
      }
      public function setName($value){
         $this->value;
      }
  }
  $stu = new stu('猪');
  echo '真的很贵哦：' . $stu->getName() . '<hr>';
  $stu->setName('灭绝师太');
  echo '讲师' . $stu->getName();
