Understand and learn all aspects of PHP framework PHP training tutorial

　　

　PHP is the most popular scripting language for many reasons: flexibility, ease of use, and more. For project development, we usually need a PHP framework to replace programmers to complete those repetitive parts. In this article, Brothers PHP Training will conduct a comprehensive analysis of the PHP framework.

　　What is a PHP framework?

　　A PHP framework provides a basic framework for building web applications, thereby simplifying the process of writing web applications in PHP. This not only saves development time, helps build more stable applications, but also reduces repetitive coding development. Frameworks can also help beginners build more stable application services, which can allow you to spend more time creating actual web applications than writing repetitive code.

　　We generally think of the PHP framework as acting like a Model View Controller. MVC is a programming architectural pattern that separates business logic from the UI, allowing individual modifications. MVC breaks the development process of an application so that components can work independently of each other, making coding in PHP faster and easier.

　　Why use a PHP framework?

　　There are many benefits for developers to use a PHP framework, one of which is to speed up the development process and save developers a lot of time and effort. In addition, stability is another important reason for developers to use frameworks. Although simplicity is the biggest advantage of PHP, and many people like to use this scripting language because of this, it is also the biggest disadvantage of PHP. Some developers, especially beginners, can easily write poor code without realizing it.

　　PHP is a very forgiving language, so it is more important to make sure there are no loopholes when programming. Finally, the use of PHP frameworks is very widespread, and there are many different frameworks to choose from. Many developers choose well-known frameworks, and they can communicate with other developers using the same framework through forums/communities, and of course you can develop your own framework. Before choosing a framework, you should ask yourself: Will it save you and other users time and effort? Will the application perform better? Will it improve stability? If you answered yes to all of these questions, Then it's time for you to choose an appropriate framework for your project.

　　When to use a PHP framework?

　　This is a question shared by both experienced and junior developers. For many beginners, a framework will provide a lot of ease and stability, so PHP frameworks should be used whenever possible. This will help reduce or eliminate bad coding and speed up the development process. On the other hand, many experienced PHP programmers see frameworks as a tool for low-level programmers who don't know how to write good code. In conclusion, when working on a project where time is tight, using a PHP framework has many benefits that can greatly speed up the coding process. Another scenario is when you are working on a project with a lot of code, you should also consider using a PHP framework as it will help reduce the tediousness of the work.

　　What are the best PHP frameworks?

　　Over the past few years, as PHP has grown into the scripting language of choice for most developers, there has been a proliferation of PHP frameworks. What is the best PHP framework, everyone sees the truth, because not every framework can be suitable for everyone. Here are some reviews of PHP frameworks:

　　◆The Zend Framework

　　Zend Framework is very popular in the developer community, with a focus on Web 2.0-style applications. Zend is known as the PHP Company due to its extensive support and active user base. Zend is definitely one, if not the most popular PHP framework out there today. Its powerful functions can meet the needs of enterprise level, of course, its use also requires extensive knowledge of PHP.

　　◆CakePHP

　　From beginners to advanced PHP developers, CakePHP is a great choice. It is designed on the same principles as Ruby on Rails, focusing on rapid development making it an excellent framework for rapid application development. Its rapidly growing support system, simplicity and extensibility make CakePHP the hottest PHP framework today.

　　◆Symfony

　　Symfony targets more advanced developers, that is, developers who create enterprise-level applications, especially Askeet and Yahoo! Bookmarks. This open source PHP framework is full-featured, but its main disadvantage is that it is slower than other frameworks.

　　◆ CodeIgniter

　　CodeIgniter is known for its ease of use, performance and speed. Unlike Symfony, CodeIgniter is primarily aimed at developers sharing hosting with others, or developers looking for a PHP framework for small devices. It offers simple solutions and has an extensive library of video tutorials, forums, user guides and wikis. Beginners should consider using CodeIgniter.

　　◆ Seagull

　　Seagull is a stable PHP framework for building web, command line and GUI applications. It's a very easy-to-use framework, ideal for beginners to advanced programmers. For beginners, Seagull has a sample application library that can be set to meet their own needs; for advanced developers, Seagull provides many choices including best practices, standards, and modular code bases, which can help quickly and easily. Build web applications. Seagull has an active developer community with extensive supporting documentation and instructions.

　　The above PHP frameworks have their own characteristics, and they are all open source projects, but the projects targeted by the frameworks are different. Generally speaking, CodeIngiter is more suitable for small projects, CakePHP and Zend Framework are more suitable for medium-sized projects, and Symfony is more suitable for large and heavyweight projects. When selecting a project, you should fully consider the customizability and extensibility of the framework, because each project cannot be sure whether you will change it as your needs change.
