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

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

Design mode (14) Iterator mode iterator (object behavior type)1. Overview Object-oriented programming in a class encapsulates the application logic. Class is an instantiated object, each individual object has a specific identity and state.

PHP design pattern: Iterator pattern (4 ). 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

Iterator (Iterator) mode, which provides an abstraction on a very common process: an iteration on a set of objects (or scalars) in an unknown part of an object graph. Iterations have several different methods of execution: Iterating over Array

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 lacks functions such as the count ()

1. Overview Class. Class is an instantiated object. Each individual object has a specific identity and status. A separate object is a useful way to organize code, but you usually process a group of objects or collections. The set is not
