__set() And __get() 使用详解.

正确姿势：

final class private_{
    private $name=‘adminmas‘;
    private $sex =‘20‘;
    public function __get($name){
        return $this->$name;
    }
    public function __set($name ,$value  ){
        $this->name = $value;
    }
}
$cl = new private_;
$cl->name = ‘jun‘;
var_dump( $cl->name );

错误姿势：

final class private_{
    static private $name=‘adminmas‘;
    private $sex =‘20‘;
    public function __get($name){
        return $this->$name;
    }
    public function __set($name ,$value  ){
        $this->name = $value;
    }
}
// $cl = new private_;
private_::$name = ‘jun‘;
var_dump( private_::$name );

总结：

__get() And __set() 魔术函数无法获得静态方式访问的属性名

必须得通过新建对象的方式访问.才能设置或获取和设置私有的属性.

ps：

PHP的高级特性：偶然间发现的.

class na{

    static private $name= ‘adminmas‘;

    //self::$name //正确

    public function __get($name){
        return self::$name; //正确
    }
}
$cl = new na;

var_dump( $cl->name );
