成员属性在两个步骤之间无法共用

成员属性在两个方法之间无法共用

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

$a在ax()中赋值之后，如何才能在bx()中调用值等于111的那个$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

PHP 类

分享到：

------解决方案--------------------
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

------解决方案--------------------

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