[英]How to clean Magento cache?
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:(该脚本发布在amartinez 的magento 论坛中)
通过 cron 作业运行
00 0 * * * root /var/www/html/magento/cron_refresh_cache.php >> /var/log/cron_refresh_cache.log
php 文件:
#!/usr/bin/php
<?php

我刚刚运行了这段代码,但出现错误提示:
Using $this when not in object context in cron_refresh_cache.php on line 34
也许amartinez是通过 magento cron 使用的,而我是通过 os cron 使用的?
无论如何,我通过创建一个类来解决它,将“refresh_cache()”函数包装在其中,并为该类提供一个名为“notify”的函数,该函数接受两个参数,然后将它们回显出来。
然后我创建了这个类的一个新实例,并调用了它的“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:
#!/usr/bin/php
