PHP design pattern series-Iterator pattern (Iterator) 1. Pattern Definition The Iterator mode is also called the Cursor mode. Provides a method to access each element in a Container object without exposing the internal details of the object. When

This article provides a detailed analysis of the Iterator mode in the PHP design mode. For more information, see the Iterator mode, it provides an abstraction in a very common process: iteration on a set of objects (or scalar) that are not part of

The protagonist of today's PHP design pattern series is the iterator (Iterator) pattern, which provides an abstraction: an iteration on a set of objects (or scalars) in an unknown part of the object graph.Iterator (Iterator) mode, which provides an

PHP design pattern: Iterator pattern (3 ). Note that the Iterator is better abstract than the object set, because we can make InfiniteIterators, NoRewindIterators, and so on without having to be consistent with the regular array. Therefore, Iterator

The Iterator mode provides an abstraction in a common process: an iteration of a set of objects (or scalar) that are located in an unknown part of an object graph. Iterations have several different execution methods: iteration over an array
