If array_walk() is the best (fast and memory efficient) way to delete elements, why have we had the following line in the manual, for the array_walk() callback, for over a decade [1]? (The exact phrasing has changed slightly one time, but the message has remained the same) "Only the values of the array may potentially be changed; its structure cannot be altered, i.e., the programmer cannot add, unset or reorder elements."
