No. end() move the internal point inside the array to the last element.
sizeof() returns the number of elements inside the array. As Pedro
illustrated, the distinction is most obvious when you have an
associative array.
Arrays in PHP are hybrid linked-lists and hash tables. Each elements
links to its neighbors and can simultanously be quickly accessed
through a hash key.
