10 recommended articles about PHP iterators

Iterator is a pattern that can separate the traversal behavior of sequence type data structures from the traversed objects. Next, I will share with you the Java Iterator through this article_Compiled by Power Node Java Academy, friends in need For reference, iterator is a pattern that can separate the traversal behavior of a sequence type data structure from the object being traversed, that is, we do not need to care about what the underlying structure of the sequence looks like. As long as you get this object, you can use an iterator to traverse the interior of this object. 1. IteratorJava provides a specialized iterator <>Iterator. We can implement this interface for a certain sequence to provide standard Java iterator. The function after the Iterator interface is implemented is to "use" an iterator. Document definition: Package java.util; publicinterface Iterator { boolean&am

3. PHP advanced object-oriented design pattern : Iterator pattern usage examples

Introduction: What is the iterator pattern? The Iterator design pattern helps construct objects that provide a single standard interface for looping or iterating over any type of countable data. Iterator Pattern Problems and Solutions: The Iterator design pattern helps style objects handle collections of data or other objects. When creating a class based on the Iterator design pattern, we also create a set of interfaces to provide a unified way to manage these collections. Sometimes, the data set seems very simple. Programmers may not anticipate changes, so they choose not to modify their code and not create iterators. This situation often occurs when calling the database. At this point, the programmer creates a MySQL query and then executes a simple fetch array command. But

Python basics iterators and generators

Introduction: Iterators are a way to access the elements of a collection. The iterator object starts accessing from the first element of the collection until all elements have been accessed. Iterators can only move forward, not backward, but that's okay since people rarely move backward during iteration. In addition, one of the great advantages of iterators is that they do not require all elements to be prepared in advance for the entire iteration process. The iterator only calculates an element when it iterates to it, and before or after that, the element may not exist or be destroyed. This feature makes it particularly suitable for traversing some huge or infinite collections, such as files of several G
