从 php laravel 禁用 memcached
Disable memcached from php laravel
你好，我正在使用 php laravel 框架编写的 cms，它有 memcached 缓存服务。
我需要从 memcached 可以是 运行 新主机的虚拟服务器迁移网站，所以我需要 disable/avoid memcache，因为网站使用 memcached 并不复杂。我怎样才能避免缓存并更改我的 php 文件。
这是我正在使用的东西

非常感谢
在您的 .env 文件（项目的根目录）中，设置以下内容：
CACHE_DRIVER=array
这将导致对缓存服务的任何调用都存储在内存中，并且纯粹是为了调用它的请求。
或者，在您的 cache.php 配置文件中，您可以更改
'default' => env('CACHE_DRIVER', 'file'),
至：
'default' => env('CACHE_DRIVER', 'array'),
如果您没有在 .env 中定义 CACHE_DRIVER，并且希望默认使用数组。
