note 30873 added to function.array-push

The entry of "12-Dec" re: use of the term "stack" vs. "queue" should be deleted. This note is entirely wrong and apt to mislead the naive. The difference between a stack and a queue is that a stack adds and removes at the same end, while a queue adds at one end and removes from the other. As for any underlying data structure, such as an array: whether an implementation of "push" operates on the top/bottom/front/back of that data structure is entirely arbitrary. ~mark -- http://www.php.net/manual/en/function.array-push.php http://master.php.net/manage/user-notes.php?action=edit+30873 http://master.php.net/manage/user-notes.php?action=delete+30873 http://master.php.net/manage/user-notes.php?action=reject+30873
