iterator interface

First, IntroductionIn my previous blog post, I shared my understanding of the command pattern, which was mainly to abstract the behavior into commands, which resulted in low coupling between the requester's behavior and the recipient's behavior. In

So that your PHP object can be foreach, and attributes are modified using Private If you are bored, you can play with it.The traversal object is actually just a specific attribute of the array type in the object.You can use foreach directly

Play a game when you are bored.Traversing an object is simply a matter of iterating through the properties of a particular array type in the object.PHP5 can be directly foreach, but private members of the class cannot access it.The object-oriented

Concept Iterator mode (Iterator), also called cursor mode. Provides a way to sequentially access various elements in an aggregated object without exposing the object's internal representation. You should consider using the iterator pattern when you

PHP design pattern: Iterator pattern (2 ). 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

This article mainly introduces six pre-defined interfaces in PHP. This article describes Traversable, Iterator, IteratorAggregate, ArrayAccess, Serializable, Closure, you can refer to PHP to describe 6 predefined interfaces as follows: 1.

Traversable is used to detect whether a class can traverse using foreach, an internal engine interface that cannot be implemented in a PHP script, and we use the iterator interface or the Iteratoraggregate interface to implement traversal in

So, to prevent this information from appearing, when I use foreach, the arguments are forced to type conversions, the situation is as follows: foreach (array) $arr as $key = = $value); This has been peaceful, just a few days ago, suddenly there was

Many interfaces are provided in php to implement some very specific functions. for example, if you want to use an object as an array, you only need to implement the ArrayAccess interface, to use an object in foreach, you only need to implement the

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 ()
