Differences and features of commonly used PHP frameworks

Common PHP framework differences and features

The TP framework is used at work. I have been exposed to the Yii framework and the Laravel framework. In order to better understand the several frameworks, here is a summary of their respective advantages and disadvantages.

1. CI framework

CI framework is a simple and fast PHP MVC lightweight framework. It has high execution efficiency, fast and concise, and small amount of code. , suitable for small and medium-sized project development, and can also be used for large-scale projects, but the scalability is not very good.

Advantages: The framework is relatively simple, suitable for entry-level development, easy to learn, quick to get started, easy to staticize, and the documentation is relatively detailed.

Disadvantages: Because the framework is small, the functions are incomplete. For example, if you use mongoDB, you need to implement the interface yourself, and the operation of the database is not safe enough (write operations). Poor support for large projects.

Development workflow:

1. index.php serves as the front-end controller to initialize the basic resources required to run CodeIgniter.

2. Router checks the HTTP request to determine who will handle the request.

3. If the cache file exists, it will bypass the usual system execution sequence and be sent directly to the browser.

4. Security. HTTP requests and any user-submitted data will be filtered before loading the ApplicationController.

5. The Controller loads models, core libraries, plug-ins, auxiliary functions, and any other resources needed to handle specific requests.

6. The final view renders the content sent to the web browser. If caching is turned on, the view is cached first so it will be available for future requests.

CI's url mode:

The url mode supported by Ci defaults to the pathinfo format, which is separated by /. Among them, //localhost/citest/index.php/ is fixed and represents the entry file

. For example: //localhost/citest/index.php/hello/index

2. ThinkPHP framework

TP framework is a fast, compatible and simple lightweight domestic PHP development framework that uses object-oriented structure and MVC mode. development. It can support servers such as Windows and Linux, and supports multiple databases and PDO extensions such as MySql and Sqlite. It contains common components such as underlying architecture, compatibility processing, base class library, database access layer, template engine, caching mechanism, plug-in mechanism, role authentication, form processing, etc., and is more convenient for cross-version, cross-platform and cross-database transplantation. . Suitable for small and medium-sized project development.

Advantages: Simple and easy to use (Model, Controller, View are responsible for their own work), it has a compiled template engine that supports XML tag library technology, supports two kinds of template tags, and dynamic compilation , caching technology. It also supports custom tag libraries, with unique data validation and auto-fill, MD5 data encryption and other functions. Deployment is simple and requires only one entry file, making it quick to get started.

Disadvantages: The template is relatively fixed, which makes it easy for ideas to solidify.

There are 4 routing forms provided in the TP framework. Among them, the rewrite routing method requires additional modifications to the configuration before it can be used. For the configuration method, see https://www.cnblogs.com/lovele-/p/9256575.html

1. Get routing mode;

//Website/index.php?m=group&c=controller&a=method (this mode is the lowest transmission method and is not safe).

2. Pathinfo routing form [default routing form]:

//URL/index.php/group/controller/method

3. rewrite routing form;

//Website/Group/Controller/Method

4. Compatible routing format:

//Website/index.php?s=/Group/Controller/Method

3. Laravel Framework

Laravel is a simple and elegant PHP WEB development framework. It integrates the relatively new features of PHP and various design patterns. It is a framework suitable for learning, but it requires a solid and proficient PHP foundation. Suitable for the development of large and medium-sized projects.

Advantages:

1. Support Composer

2. The framework structure is relatively clear and focuses on the modularization of the code (abstracting middleware, tasks, services, etc.) and scalability, the routing system is fast and efficient

3. Supports processing of cross-site request forgery. When submitting form form post, {{ csrf_field() }}

## must be passed in #4. Laravel's community is very strong, with rich extension packages and tools

5. It has functions such as caching, authentication, task automation, hash encryption, transactions, etc.

6. It is unique. env environment file facilitates system configuration and development of different platforms

Disadvantages: Based on a component-based framework, it is relatively bloated

Laravel routing method: laravel routing The functions are very powerful, including

1. Basic routing Route::get('/',function(){ return'HelloWorld';});

2. Route with parameters Route:: get('user/{id}', function($id){ return 'User '.$id;});

3. Route filtering parameters Route::get('user/{id}/{name}',function($id,$name){ //}) -> where(array('id'=> ; '[0-9] ', 'name' =>'[a-z] '));

4. Subdomain name routing, etc.

5. Controller routing, For example, some of the styles below

Route::resource('article','ArticleController'); //restful方式(具体包括get/post等)

　　Route::controller('article','ArticleController'); //restful方式(具体包括get/post等)

　　Route::get('user/login','UserController@login');//非restful方式 get

　　Route::post('user/i','UserController@login');//非restful方式post

4. Yii Framework

Yii Framework is a high-performance PHP open source framework based on components for large-scale web application development. One of the most efficient PHP frameworks currently available. Suitable for large-scale heavy-duty web application development.

Advantages:

1. Pure OOP development, easy to use model

2. Supports command line tool development, you can quickly create a web application Program code

3. Highly reusable and scalable

4. Fast development speed, excellent performance and rich functions

5. Support composer package management Tool

Disadvantages: The model layer is less considered and there are fewer Chinese documents in the document. It requires proficiency in PHP technology and proficiency in OOP programming
