Bug description:Internal Cursors
Description:
------------
https://github.com/php/php-langspec/blob/master/spec/12-arrays.md#arrays
The concept of an array's internal cursor or an object's internal
cursor is never mentioned. The state of the internal cursor of an array
or object can be witnessed via the current(), key(), next(), prev(),
reset(), end(), and each() library functions. While it's technically
library functions that expose the state of the cursor to the programmer,
you can find code deep in the core array/object implementation of PHP5
that deals with and maintains internal cursors. Also, internal cursors
get mentioned in various parts of the php.net documentation, including
the documentation for "foreach", so internal cursors are arguably a
language feature.
