Question

laravel5.2 There is a cache on the page, but refreshing does not work. The cache becomes invalid after waiting for a few minutes. What is the reason?

APP_ENV=local
APP_DEBUG=true

If these two are configured like this, there should be no caching.

Answer 1

The problem is solved because PHP5.6+ has opcache enabled by default
