Laravel is an open source Web framework developed by Taylor Otwell based on the PHP language, which adopts the architectural model of MVC and officially released its first version in June 2011-the first Commit of Laravel.

Because Laravel has excellent characteristics such as Rails agile development, the deep integration of PHP's powerful Composer ecology and the broad audience of PHP developers has made Laravel develop rapidly in just a few years after its release. From the trend chart provided by Google Trends (figure 1.1), we can see that the growth rate of Laravel framework in the past seven years is the fastest in all kinds of PHP frameworks, which directly reflects the strength of Laravel and its considerable development prospects in the future.

Why use Laravel?

Laravel is a precise PHP framework that seamlessly meets the development needs of open source applications of all sizes and is an ideal choice for developers. Its huge community support can quickly solve programming problems. In addition, it provides a learning forum.

Why is Laravel the best PHP framework?

Laravel has become the best PHP framework because of its excellent and rich features. For example, development companies can use laravel advanced features to create compelling and based on high performance

What are the main functions of the Laravel framework?

1. Innovative template engine

The Laravel framework is widely recognized for its built-in lightweight templates that can be used to build layouts with dynamic content. It also provides basic widgets that use its structure to integrate CSS and JS code. Laravel templates are carefully designed to develop simple layouts and partial composite layouts, thus simplifying the work of developers.

two。 Support MVC architecture through built-in functionality

Laravel supports the MVC architecture pattern, which ensures that important business logic is separated from the presentation layer. Laravel's MVC mode has several built-in features to improve application performance, security, and scalability.

3. Coding authorization technology

Authorization and authentication are the most important functions when we generate the code to build the application. It can also assess the time it takes programmers to build new content. The framework even has logical techniques that can help reform authorization logic and control access to different resources.

Because the verification computer code is integrated into Laravel, the coding time is effectively reduced. Its application reasoning function provides programmers with flexibility and freedom to work flexibly on software of all sizes.

4. Object-relational mapping and implementation

Laravel provides object-relational mapping (ORM), which is implemented in combination with simple PHP Active Record. This feature helps enable Web application developers to write database queries using PHP syntax instead of writing SQL code. And ORM is faster than the previous PHP framework.

5. Strong application security

Security is one of the best features of Laravel. The Laravel framework provides advanced and powerful security for Web applications, making it easy for developers to use. The Laravel security feature makes effective use of salt hashing and cryptographic mechanisms, so it does not save passwords in plain text to the user database.

It also uses the Bcrypt hash algorithm to create encrypted passwords. In addition, this PHP Web development framework uses SQL statements to protect SQL injection.

6. Artisan tool for automating programming tasks

The Laravel framework provides a built-in command-line tool for Artisan to help us automate tedious and repetitive programming tasks. The artisan tool is also used to build database structure and framework code. It is further used to deal with migration libraries, so it is very convenient to manage various databases.

In addition, it can generate raw MVC files from the command line and process them with its configuration. Artisan even assists developers in generating commands and using them as needed.

7. Enable libraries and modular features

Laravel facilitates developers with pre-installed object-oriented and modularization libraries, some of which are not accessible in other PHP frameworks but work properly in Laravel. For example, it is very simple to implement an authentication library and can have a variety of functions.

These features include checking active users, password reset, Bcrypt hashing, CSRF (cross-site request forgery) protection, and encryption. In addition, the framework is divided into units that adopt advanced PHP principles, thus realizing the development of responsive and modular Web applications.

8. Simplify the database migration system through PHP code

The Laravel migration feature helps extend the Web application database structure so that it does not need to be recreated every time a change is made in the code. This feature greatly reduces the risk of data loss.

This function not only provides the ability to change the overall structure of the database, but also provides some additional functions. It can even better facilitate the use of PHP code. In addition, Laravel Schema Builder can help developers generate database tables and insert indexes with required columns at a specified time.

9. Competitive and easy unit testing

Laravel is an ideal framework for Web application developers because it facilitates unit testing capabilities effectively and easily. The framework is capable of running a large number of unit tests to prevent programmers from making changes to existing Web applications, thereby preventing programmers from making new changes. Ideally, a Laravel-based Web application can be released stably because it can identify faults and issue warnings. For developers, writing unit tests is also effortless.

10. A useful tutorial

Laravel provides convenient learning resources for beginners and experienced developers. Whether you are browsing free video tutorials or paid services, you can learn how to use Laravel. The learning instructions provided are up-to-date and easy to understand, making it easy to learn the technical framework.

Advantages of the Laravel framework

1. Laravel framework can realize authentication without worry. Everything is properly configured with well-organized authorization logic and the required controlled access to various resources.

2. The framework provides a clean, easy-to-use API through the SwiftMailer library. Laravel also provides drivers that allow applications to start quickly and send emails or notifications through local or cloud-enabled services.

3. Laravel supports the popular caching backend, so developers can quickly configure caching.

4. Laravel integrates with the advanced Monolog log library, which is very helpful to developers, which provides technical support for a series of powerful log handlers.

5. Each Laravel route is defined in the app / Http / routes.php file, which is automatically loaded by the framework. It also accepts URL and closures and provides a powerful way to identify routing.

6. advanced design ideas, using facade patterns, control inversion, dependency injection and other design patterns, strong expansibility

7. Active community and many open source projects

8. Testing is convenient. Laravel integrates all the php tests of phpunit. In addition, it also has some testing assistance methods, including the simple use of complex database data problems under phpunit. Laravel provides some options for testing. It can also test the database without affecting the actual database. In addition, it can be said to be very convenient to test elements in the browser, such as buttons, links, etc. Laravel supports phpunit, database testing, HTTP request testing, and browser element testing.

9, and Eloquent's powerful database relational mapping model, in the process of writing a website, dealing with data is actually the big head, while Laravel uses Eloquent, what does it mean? If you have a user datasheet User and an article datasheet Post, you just need to declare a user () method in PostController and write $this- > belongsTo () in it, so that the one-to-many relationship between the user and the article is established, and then call $post- > user to get the owning users of this article, isn't it convenient? This is just one of the relationships, and Eloqent works well for a variety of complex databases.

10. Tinker's debugging function for php. Seeing here, you might say that php also has debugging function? Of course, the debugging function here is not a breakpoint like in java or C++, but REPL (read-evaluate-output-loop). If you are familiar with python, this should be very simple, such as entering tinker, and then in the command line interface, enter echo 'hello world', it will immediately output hello world, of course, this function is very simple, but all other php statements can be run in tinker, and even you can define variables.

11. The factory generates data factory, which is also aimed at testing. For example, if you need a lot of user data locally, you can directly create a user factory, and then you can immediately generate 50 pieces of data to the database by typing factory (user, 50)-> create (). Of course, you can also use make, so that only the data is generated and not saved to the database, and Laravel allows you to choose the type of data to generate. Such as words, sentences, paragraphs, numbers and so on.

12, powerful blade view template language, in PHP, you may often encounter to output the same form elements, or error display errors, etc., you can define these in a file, such as error.blade.php, and then need this template only include (error), this can reduce a lot of repetitive code, and blade supports the transfer of variables, for the mvc pattern, this blade template language is very convenient.

13, powerful form validation function, only need to write a validation function, Laravel will deal with the form fields.

Important points

The above features of Laravel make it work incisively and vividly in the entire developer community and are very useful to some people. It continues to attract new users among developers through its classic architecture. This architecture has become an open place for different developers to create their own feature sets for various projects.
