Question

我需要一个简单的脚本来刷新Magento缓存的每个元素。我正在运行1.3.2.3并且无法升级。

用于刷新magento缓存的示例cron作业脚本： （该剧本由 amartinez 在magento论坛上发表）

通过cron job运行

00  0 * * *   root /var/www/html/magento/cron_refresh_cache.php >> /var/log/cron_refresh_cache.log

php文件：

我刚刚运行此代码，我收到一条错误消息：

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

也许 amartinez 通过magento cron使用它，而我使用的是os cron？

无论如何，我通过创建一个类来解决它，在其中包含“refresh_cache（）”函数，并且还为类提供了一个名为“notify”的函数，该函数接受了两个参数，并且只是回显了它们。

然后我创建了这个类的新实例并调用了它的“refresh_cache”方法，而不是像原始代码一样直接调用“refresh_cache（）”。

这是我修改后的代码：

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