Note Submitter: ashnazg at php dot net ---- Regarding michaeln's note about registering __destruct() resulting in the destructor being called twice. This is true since some PHP5 version. Doing this step was likely only a tactic in PHP4, in which it worked as expected. However, once upgrading to PHP5, you'll want to look for and likely remove such usage from your code.
