类似这样:

class MyClass {  private $index;  public function __construct($index) {    if ($index === 0) {      // 销毁对象    }    $this->index = $index;  }  public function getIndex() {    return $this->index;  }}$t = new MyClass(1);echo $t->getIndex(); // 正确返回$t = new MyCalss(0);echo $t->getIndex(); // 失败。

回复讨论(解决方案)

为什么要这样?还是要单例模式?

把$t对象销毁了,就没有引用了

私有化构造函数

单例模式试试呗

找到了,直接在里边trigger_error了
