PHP 类

class a {    public $a=0;     public fucntion ax(){        $this->a='111';     }    public fucntion bx(){        echo $this->a;     }}

$a在ax()中赋值之后,如何才能在bx()中调用值等于111的那个$a?在一个方法中给一个属性赋值之后另一个方法无法获得那个值


回复讨论(解决方案)

你的function写错了。。。。

实例化后按顺序执行 ax,bx 就有了
你要明白一点,ax/bx在类内是平行的,不是说你写在前面,后面的就有值

class a {    public $a=0;     public fucntion a(){        $this->a='111';     }     public fucntion bx(){        echo $this->a;     }}

复制我的代码,运行就可以了。 function 拼写错误,自行修改。

class a {    public $a=0;     public function a(){        return $this->a='111';     }     public function bx(){        echo $this->a();     }}$p = new a();$p->bx();
