have to do this manually?
Yes.
So 'unset($some_big_array)' or 'unset($some_big_object)' etc.. is the
right way to go for non-resource based items? i.e. it needs to be
explicitly done?
It's not quite like C - if you reassign something, the previous contents
are automagically freed. I use unset() if I know it could be a while
(hours) before it'll likely be reassigned, but it won't be used in the
meantime.
Has anybody done a comparison of setting to null rather than unset'ing;
does unset invoke the garbage collector instantly? i.e. is unset the
best approach to clearing objects from memory quickly?
Best,
