A comparison of the advantages and disadvantages of several mainstream PHP frameworks, a comparison of the advantages and disadvantages of the php framework

PHP is an open source server-side script development language that is popular at home and abroad. Able to adapt to the development needs of large, medium and small projects. In this article, we will introduce to you several mainstream PHP frameworks and their related advantages and disadvantages, and share them with friends as a reference.

The main reference PHP frameworks include: CodeIgniter, CakePHP, ZendFramework, Symfony. I have not used many frameworks seriously, I just tried them briefly. Many of my opinions may be immature or wrong. Please correct me and let us grow together.

　CodeIgniter

　Advantages:

1. The configuration is simple, all configurations are configured using PHP scripts, and the execution efficiency is high; it has basic routing functions and can perform routing to a certain extent; it has preliminary Layout functions and can create a certain degree of interface appearance; database layer Well packaged, with basic MVC functions

　2. Fast and concise, not much code, high execution performance, simple PHP framework, easy to use, low learning cost, detailed documentation; it comes with many simple and easy-to-use libraries, and the framework is suitable for small applications

　Disadvantages:

1. Simply understand the Model layer as a database operation

2. The PHP framework is slightly simple and can only meet the needs of small applications, but is slightly less able to meet the needs of medium-sized applications

　Rating:

Generally speaking, it is worthwhile to use CodeIgniter to complete simple and fast applications. At the same time, it can construct a certain degree of layout to facilitate the reuse of templates. The data operation layer is well encapsulated, and CodeIgniter does not use many complicated designs. Mode, execution performance and code readability are all good. As for the additional library, it is not bad, simple and efficient.

　CakePHP

　Advantages:

　1. CakePHP is the PHP framework most similar to RoR, including the design method and the Active Record method of database operation; the design level is very elegant, there is no extra library, all functions are pure frameworks, and the execution efficiency is still high Not bad; the hasOne and hasMany functions of the database layer are very powerful and suitable for complex business processing; the routing function and configuration function are not bad; the automatic scaffolding (scaffold) is very powerful; suitable for medium-sized applications; it has basically implemented every layer of MVC; it has Automatically operate command line script function;

2. The documentation is relatively complete and has been successfully promoted in China. Most people know CakePHP and the learning cost is medium

　Disadvantages:

1. A very serious problem with CakePHP is that it understands Model as a database layer operation, which seriously affects its ability to operate other than the database

2. CakePHP’s cache function is slightly weak, and its configuration function is slightly weak; CakePHP is not suitable for large applications, only medium-sized applications, and the learning cost is slightly higher for small applications

　Rating:

Generally speaking, the CakePHP framework represents a very important era and representative of the PHP framework, and currently plays a very important role. Many self-written frameworks imitate the CakePHP method, which is a landmark product; CakePHP revealed With RoR's agile development method and the design philosophy of considering database operations as the only model, it is an excellent tool for developing rapid applications and prototypes; similarly, it is also worth choosing as a development framework for Web 2.0 websites.

　Zend Framework

　Advantages:

1. An official product, it comes with a lot of libraries. The framework itself is written using many design patterns. The architecture is very elegant and the execution efficiency is medium. The MVC design is relatively simple, has routing functions, and the configuration file is relatively powerful. (Able to handle XML and php INI), various libraries are very powerful, and have the most comprehensive functions among all PHP frameworks, including that it is not only a PHP framework, but also a large class library (replacing PEAR), which is its Main features: It can intuitively support the Model layer in addition to database operations (better than CodeIgniter and CakePHP), and can easily use the Loader function to load other newly added Classes; the Cache function is very powerful, from the front-end Cache to the back-end Cache All are supported. The back-end Cache supports Memcache, APC, SQLite, files, etc.; the database operation function is very powerful and supports various drivers (adapters)

　2. The documentation is very complete, the domestic community is very mature, and is currently used by many Web 2.0 websites, and the learning cost is medium

　Disadvantages:

1. The MVC function is relatively weak, the View layer is simply implemented (the same as not implemented), and it cannot control the front-end page very powerfully

2. Without automated scripts, creating an application, including entry files, must be built manually, and the entry cost is high

　3. Zend Framework is not a big problem as a medium-sized application framework, and it can barely be used as a PHP framework for large-scale applications. However, as a very mature large-scale PHP framework, it still needs some effort

　Rating:

As an official framework, Zend Framework’s ambition is foreseeable. It wants to crowd out other frameworks, while encapsulating many powerful class libraries to provide one-stop framework services, and their development team is very strong. It is fully capable of developing very powerful products, so it is basically certain that Zend Framework has a bright future, if more time is spent to improve the framework. Similarly, the Zend Framework architecture itself is relatively elegant, which shows that Zend officially has many experts and is relatively advanced in design concepts. Although some functions are not fully implemented, such as the View layer, automation scripts, etc., these all depend on the future. upgrade. Generally speaking, Zend Framework is the most anticipated PHP framework. Of course, there is no problem if you want to use it in your project now.

　Symfony

　Advantages

　1. Symfony is the most powerful PHP framework I know, and I have been using it for a long time, but many functions have not yet been discovered; it fully implements the three layers of MVC and encapsulates everything, including $_POST , $_GET data, exception handling, debugging function, data detection; includes powerful caching function, automatic loading of Class (this function is very cool), powerful i18n nationalization support; has very powerful view layer operation, and can include individual Multiple files; very powerful configuration function. Using yml configuration can control all frameworks and program running behaviors, which is so powerful that it makes people speechless; you can define various classes of your own at will, and symfony can automatically load these classes , can be called at will in the program; includes powerful multi-level project and application management: Project --> Application --> Module --> Action, which can meet the needs of multiple applications under one project, and each layer can Define your own class library, configuration file, layout; very powerful command line operation functions, including creating projects, building applications, building modules, refreshing cache, etc.;

2. Symfony is definitely the first choice for developing large and complex projects, because using Symfony will greatly save development costs, and there will be no problems when multiple people collaborate. After the basic Class is defined at the Project level, any module can Able to reuse, greatly reuse code

　Disadvantages:

1. The database operation model uses heavyweight prop and creole, but in the version I tested, they have been moved to addon, which can be used or not

　2. The cache function cannot be controlled. The cache is always cached every time during development and debugging. You need to execute symfony cc, symfony rc to clear and rebuild the cache;

3. The efficiency is not very high, especially the process of parsing templates and reading configuration files, which takes a lot of time;

　4. The learning cost is very high, and there is no mature community and documentation in China, not even a Chinese manual. Accordingly, it takes a lot of time to master all the functions

　Rating:

Symfony is definitely an enterprise-level PHP framework, the only one that can seemingly compete with the powerful frameworks in the Java field. Powerful things are naturally complicated to learn, but they are also helpful for project development, so complex ones are naturally recommended. The project is handled using Symfony, which I think is worthwhile. The later maintenance costs are relatively low and the reusability is very strong. Correspondingly, if you use Symfony for more complex Internet projects, you must consider the issue of database distribution. Then you need to abandon the database operation layer that comes with Symfony and define it yourself. Of course, Symfony supports arbitrary Construct the model layer.

Summary

The above PHP frameworks have their own characteristics, and they are all open source projects. However, 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-scale projects. level projects, when selecting projects, you must fully consider the customizability and scalability of the framework, because each project cannot determine whether you will make changes as the needs change.

Relatively speaking, Zend Framework and Symfony have strong ability to cope with changes, especially the ability to customize the Class of the model layer at will, which makes it very convenient to add your own business or data processing classes. I personally recommend them for use in medium and large projects. PHP framework.

CodeIngiter and CakePHP can also play a significant role in small and medium-sized projects, rapid development and prototype construction, and are very suitable for the development of prototype projects with unclear goals.
