Re: [PHP-DEV] RE: PHP 4.0 Bug #8106 Updated: array_pop problem when using against an array returned from a class From: Andi Gutmans (andi <email protected>)

I think array_pop() returns NULL to indicate it has no further elements.
This is just in case you are saving bool() values in the array. It makes
more sense.
