我刚刚运行此代码，收到一条错误消息：


不在 cron_refresh_cache.php 第 34 行的对象上下文中时使用 $this

也许 amartinez 是通过 magento cron 使用它，而我是从 os cron 使用它？

不管怎样，我通过创建一个类，在其中包装“refresh_cache()”函数，并为该类提供一个名为“notify”的函数来解决这个问题，该函数接受两个参数，并且只是将它们回显出来。

然后我创建了这个类的一个新实例，并调用它的“refresh_cache”方法，而不是像原始代码那样直接调用“refresh_cache()”。

这是我修改后的代码：

I just ran this code and I got an error saying:


Using $this when not in object context in cron_refresh_cache.php on line 34

Maybe amartinez was using it via the magento cron whereas I was using from the os cron?

Anyways, I solved it by creating a class, wrapping the "refresh_cache()" function in it, and also giving the class a function called "notify" which accepted two parameters, and which just echoed them out.

Then I created a new instance of this class and called its "refresh_cache" method instead of directly calling "refresh_cache()" like the original code.

Here's my modified code:
