fuzzy76’s picture

It is probably never a good idea to call this function without a name. In theory it should be a safe operation, but in reality a lot of modules will freak out if their static variables go missing.

heathdutton’s picture

The static variables wouldn't go missing, they would be reset to their defaults. Presumably if drupal_static is used as a short-term caching mechanism in all the methods (as intended) this is fine. It's good to be cautious, but if you are running out of ram drupal_static_reset() could be the best viable option.

Xenza’s picture

Modules often use drupal_static to keep track of data from multiple calls to the same function in the current request.
As an example, please see how it is used in views_ui here: https://api.drupal.org/api/views/includes!admin.inc/function/views_ui_ad...
