Comparison of the advantages and disadvantages of several mainstream PHP frameworks

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. Simple configuration, all configurations are configured using PHP scripts, with high execution efficiency; it has basic routing functions , capable of routing to a certain extent; has preliminary Layout function and can create a certain level of interface appearance; the database layer is well encapsulated and has basic MVC functions

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

Disadvantages:

1. Keep the Model layer simple It is understood as database operation

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

Evaluation:

Overall , it is still 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 too complex design patterns, execution performance and code Readability is 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 design method and 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 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 construction of scaffolding (scaffold) is very powerful; suitable for medium-sized applications; it has basically implemented every layer of MVC; it has the function of automatically operating command line scripts;

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

Disadvantages:

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

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

Evaluation :

Generally speaking, the CakePHP framework represents a very important era and representative of the PHP framework, and it currently plays a very important role. Many self-written frameworks imitate the CakePHP method, which is a milestone. Product; CakePHP reveals RoR's agile development method and the design idea 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 Web2.0 websites. of.

Zend Framework

Advantages:

1. Official product, comes with a lot of libraries, and the framework itself is written using many design patterns , the architecture is very elegant, the execution efficiency is medium; in the MVC design, it is relatively simple, has routing functions, the configuration file is relatively powerful (can handle XML and php INI), various libraries are very powerful, and it is the most comprehensive function 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 feature; it can intuitively support the Model layer in addition to database operations (stronger than CodeIgniter and CakePHP), and can It is easy to use the Loader function to load other newly added Classes; the Cache function is very powerful, and is supported from the front-end Cache to the back-end Cache. 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, it is very mature in the domestic community, 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 if it is not implemented), and the front-end page cannot be powerfully controlled

2. There is no automated script, and you must create an application, including the entry file, all by yourself Manual construction, high entry cost

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 Efforts

Evaluation:

As an officially produced framework, Zend Framework’s ambition is foreseeable. It wants to squeeze out other frameworks, while encapsulating many powerful class libraries to provide a one-stop solution. framework services, and their development team is very strong, 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 suitable for developing large and complex projects The first choice, because using Symfony will greatly save development costs, and there will be no problems when multiple people collaborate. After defining the basic Class at the Project level, any module can be reused, greatly reusing code

Disadvantages:

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

2. Caching function Uncontrollable, 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 costs a lot It 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

Evaluation:

Symfony is definitely an enterprise-level PHP framework, the only thing that can seemingly compete with the powerful frameworks in the Java field; powerful things are naturally complicated to learn, but they are also relatively helpful for project development. , naturally it is recommended to use Symfony to handle complex projects. I think it is worthwhile. The maintenance cost in the later period is 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 For projects, CakePHP and Zend Framework are more suitable for medium-sized projects, and Symfony is more suitable for large-scale heavyweight projects. When selecting a project, you must fully consider the customizability and scalability of the framework, because each project cannot be sure whether you will follow it. Changes as needs change.

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

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.
