php的基础问题请教一下
class Test1 {<br /> static private $_name;<br /><br />}<br /><br /><br />$_test1 = new Test1('张三');<br />var_dump($_test1);
页面输出的是:
object(Test1)#1 (0) { }
我实例化的时候还传递了参数,但是Test1的类中我没有写构造方法__construct(),为什么不会报错呢?
------解决思路----------------------
构造方法也不是必须的,你传参数进去,它不执行就是了
------解决思路----------------------
构造函数已知都在,你不定义只是那个函数为空。
------解决思路----------------------
但
class Test1 {
static private $_name;
}
并没有定义构造函数 __construct
