class Person{    public $name;    public $age;    function _construct($name,$age){        $this->name=$name;        $this->age=$age;    }    function say(){        echo "my name is".$this->name."my age is".$this->age."
"; }}$person1=new Person("jack","30");$person1->say();$person2=new Person("mike","25");$person2->say();

PHP新手,學習到了物件導向來了,反反覆複的檢查了以上代碼,沒發覺有什麼問題,可就是不能輸出名字與年齡,存取範圍好像也沒超出啊。輸出只顯示 my name is my age is 。。求解答,感激不盡,如果有時間,懇請詳細解答。

_construct --> __construct

構造方法的名字寫錯了,前面是2個dash

看來樓主還不懂什麼是構造方法,看手冊吧
