How do I empty Drupal Cache (without Devel)

Question

How do I empty the Drupal caches:

• without the Devel module
• without running some PHP Statement in a new node etc.
• without going into the database itself

Effectively, how do you instruct an end user to clear his caches?

Answer 1

When you are logged as an admin (obviously, not every user of the site has to power to clear the cache), there should be a page in "Administer > Site Configuration > Performance".

And, at the bottom of the page, there should be a button (something like "Clear cached data") to clear the cache

As far as I remember, there's no need for Devel to do that, and you really don't need to go to the database, nor run some home-made PHP code.

As a reference, you can take a look at How to Clear Drupal Server-side cache

Answer 2

You can also use the Drush module, which allows you to use the command line to execute popular Drupal commands, like "drush cron" or "drush cache clear".

Answer 3

If you want to clear the cache from a module, you can use the following code.

drupal_flush_all_caches();
