Re: PHP 4.0 Bug #8378: unsetting a global array

this was explained just yesterday by Zeev Suraski: function unsetArray() { global $array; unset($array); } local $array variable referencing global $array is created in this function. when you unset $array, you unset the _local_ $array, breaking the reference only. global $array still exists. unset( $GLOBALS['array'] ) unsets $array in the global namespace. that is not a bug, that's how it works.
