我遇到了一个有时会发生的严重问题。错误消息是“致命错误：在 /var/www/quantum-framework-0.9.1-ns-alpha/class/log/LogFacility.class.php 中的非对象上调用成员函数 elapsed()第 40 行

这是代码 - 第 40 行是 $this->timer->elapsed()-thing：

public function __construct() {
    parent::__construct();

    $this->timer        = new \core\base\Timing();
    print_r($this);
    $this->timer_start  = $this->timer->elapsed();

    [...]
}

print_r($this) 的输出是：

core\log\LogFacility Object
(
    [level:core\log\LogFacility:private] => TRACE
    [file:core\log\LogFacility:private] => 
    [filename:core\log\LogFacility:private] => 
    [enabled:core\log\LogFacility:private] => 
    [timer:core\log\LogFacility:private] => core\base\Timing Object
        (
            [start:core\base\Timing:private] => 1371141304.0793
            [stop:core\base\Timing:private] => 0
            [q:core\base\Quobject:private] => 
            [supported_vars:protected] => Array
                (
                )

        )

    [timer_start:core\log\LogFacility:private] => 
    [logs:core\log\LogFacility:private] => Array
        (
        )

    [supported_vars:protected] => Array
        (
            [0] => level
            [1] => filename
            [2] => enabled
        )

    [q:core\base\Quobject:private] => core\log\LogFacility
)

那么，这怎么可能发生呢？请记住，该错误仅在有时发生 - 主要是当我更改与此计时测量功能无关的其他文件时，此外（如您所见）我在上面创建的对象存在。

哦，顺便说一句， elapsed() 方法存在并且是公开的。

谢谢你的回答！
