* A Collection resembles the nature of a regular PHP array. That is,

*
* A Collection has an internal iterator just like a PHP array. In addition,
* a Collection can be iterated with external iterators, which is preferrable.
* To use an external iterator simply use the foreach language construct to
* iterate over the collection (which calls {@link getIterator()} internally) or

* used to iterate over the collection.
* You can not rely on the internal iterator of the collection being at a certain
* position unless you explicitly positioned it before. Prefer iteration with
