Let's look at how to implement a self-defined iterator and then begin to understand how the iterator works internally. Let's take a look at an official example:Phpclass Myiterator implements Iterator { private $position = 0; Private $array =

Heavy-duty operators are good young people, but we often write a lot of repeated code for heavy-duty operators. This is boring, but it is also necessary. The more you load, the greater the elasticity of your class. However, you cannot do whatever

The difference between. End () and. Parent () is that the former is not only able to find the parent node but also the neighboring node. Toggleclass () refers to the conversion between the specified style and the default style.. Offset () is the

How does jquery obtain the address bar parameters and change the style of the address bar? Next, I will share with you the special effect code Summary of matching the jquery address bar link with the tag link through this article, if you need such a

So when I saw this article, I just learned that there was a dba function available. Well, I carefully read the dba function installtion, it is found that the support for inifile is also implemented from PHP5. Well, you can refer to the following for

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

In the **php5.5.0** version, a new generator * (generators) * feature was added to simplify the complexity of implementing an Iterator interface * (Iterator) * To create a simple iterator. With the generator, we can easily iterate through a foreach

In php, how does one make the object perform a foreach loop like an array? The following small series will introduce you in detail! If you need a friend, you can refer to the Iterator mode. I did not consider the Iterator mode when I first came into

The Fibonacci series is usually implemented using recursion, and there are other methods. It is now commercially available. it is almost no difficulty to use the PHP iterator to implement a Fibonacci series, just to rewrite the next () method in the

Check the internal execution process of the PHP iterator. Next we will learn how to implement a custom iterator, and then start to understand the internal working principle of the iterator. Let's take a look at an official example: position0;}

I don't know what to say, because when I read the INI file, I often use a ready-made Function: parse_ini_file or parse_ini_string, but how to write data is another method (implemented by myself ....) So when I saw this article, I just learned that

This is a creation in Article, where the information may have evolved or changed. The Go language delay function defer acts as a cry...catch and is very easy to use, but in practical applications, many gopher do not really understand the order of

This article describes how to use the mini program swiper to create a tab switch to implement code. For more information, see the following article. This article describes how to use the mini program swiper to create a tab switch to implement code,

This time to bring you a PHP-based implementation of the iterator steps in detail, PHP based on the implementation of a SPL iterator considerations, the following is the actual case, together to see. Now there are two classes, Department department,

This article mainly introduces the PHP based on the implementation of the iterator model, a simple description of the concept of the iterator pattern, the principle and analysis of PHP using SPL to implement the iterator mode of the relevant

Php array function for php paging // Php paging code $ Array = array ("1", "2", "3", "4", "5", "6", "7", "8 ", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18 ", "19", "20"); // specifies the array to
