drupal_static() is not equivalent to PHP static. The example you've given is using PHP static and yes, it will not be available in another function. http://api.drupal.org/api/drupal/includes%21bootstrap.inc/function/drupal_st...

I know we are going OT, but I also want to understand this;
what about:
function mymodule_complex_calculation() { static $cache; if (isset($cache)) { return $cache; } // Otherwise we need to perform our calculations // ...some complex calculation that returns $cache = complex_calculation(); return $cache; }

You are saying that if I instantiate a variable in "mymodule_impersonate()" it will not be available in "mymodule_unimpersonate()"?

You "think" wrongly. A static variable has local scope to the function declaring the static variable.

I think static are also available to other functions, use them to store cached information across my code and they work.

Static variables are only saved for a single function. Global variables are available to all functions during a single page request. Session variables are available to all page requests during a session.

Darren, thanks for the link. What is the difference between using global or static to save the data?

My code was from a module where impersonation recursively could happen, this is why I use a stack to save user state. I am also saving it to session and not using a static variable because I may uses batch functions.
But I see some problems right now: - To be safe impersonation should be saved into static variables (and "using session_save_session(FALSE);" ), so if anything goes wrong, $user is not afected. - If I want to be able to execute every Rules action in a batch, I need to change user "per action"
Any idea of how to "inject" code before and after a rule action?

We do the latter simple trick in our store code so we can show people the member prices. We have a dummy id that is a member so we switch to it, pick up the price and use it so we can show both member and non-member prices on the screen.
