Re: [Phplib-users] how to save array pointer with phplib

[nathan r. h. <na...@ds...>]

Yeppers, phplib serializes the data in your array and stores it to
whatever container you've setup (file, db, etc..) when the session object
unserializes your array and "re-constitutes" it and really does that, it
makes a new array with the name found in persistent_slot and then re-adds
the serailized data to it.

Your method of saving the pointer postion is what you need to do.  I don't
think that you can actually "save" a pointer, so you may want to find the
current location in the array, determinie it's index number and save that.

I think this would be a good feature to have for phplib to do
transparently, please file a SF Feature Requiest for it adn we'll try to
get it in to a future release.
