Everything you need to know about the PHP Laravel framework
Laravel is an open-source PHP (Hypertext Preprocessor) framework developers use to build websites. The PHP framework provides developers with a library of pre-programmed modules that they can use to quickly build web applications.
While many people accuse PHP of being "dead," developers worldwide still use it. Statistics show that nearly 78.9% of all websites with a known server-side programming language use PHP.
Laravel offers a rich set of functionalities.
Instead of using the standard PHP programming language, the Laravel PHP framework employs a scripting language. Despite their similarities, scripting languages and programming languages differ in several important ways, most notably in their usability and speed of execution.
Applications created using scripting languages are compiled at runtime, which means that each instruction is interpreted individually, making the application slower than a precompiled one. Runtime compilation also causes the application to stop or shut down if it encounters a runtime error; in contrast, precompiled applications perform error checking during compilation, making them more robust at runtime. However, for many users, the disadvantages of scripting languages are more than offset by their ease of use and iteration.
Laravel has a large growing community as it is an open-source PHP framework.
First, it's important to note that Laravel uses PHP, a scripting language, not a general-purpose programming language (usually referred to as a "programming language").
While scripting and programming languages are similar, scripting languages are platform-specific and compiled at runtime, while programming languages are not platform-specific and collected at compile-time.
Second, you must know that Laravel uses Model View Controller (MVC) architecture. MVC is an architectural pattern that uses three components.
Some of Laravel's most popular features include:
- Complete authentication system: Helps developers work securely
- Object-Relational Mapping (ORM): Helps developers use tables more efficiently
- Module Library: Developers use it to build applications without writing code
- Command Line Interface (CLI) with built-in commands: Developers use them to build, debug, and test their applications
- Automated Testing: Helps developers speed up the testing process
How Does Laravel Work?
To best understand what Laravel can do, it is essential to understand how Laravel handles requests and the request lifecycle. As mentioned above, Laravel is based on the MVC architecture and responds to user requests that the controller uses to retrieve and process data from the model and present information back to the user in the view.
The request enters the Laravel application through the public/index.php file, which loads the rest of the framework and the Laravel application instance. After the application instance is loaded, the request is routed to the console or HTTP core.
Among other tasks, the kernel defines a selection of bootstrappers that perform functions that must be completed before requests can be processed and also defines any middleware that requests must pass through before being processed. These preliminary tasks include loading all the service providers required for the application.
Once bootstrapping is complete and service providers have been registered, it forwards the request to the router, which then routes the request to a routing or controller. In addition, the router runs any required route-specific middleware. After the request has passed through all the middleware necessary, the execution of the controller's path or method will return a response that will be given back through the string to the View.
1. MVC Support and Object-Oriented Approach
The best advantage of using the Laravel framework is that it follows architectural patterns based on model, view, and controller and has a distinct, beautiful syntax that makes it object-oriented.
2. Built-In Authentication and Authorization
Laravel provides a default configuration for the authentication and authorization system. With a few crafting commands, your application will be equipped with secure authentication and authorization.
3. Packaging System
A packaging system deals more with supporting software or libraries that help a web application automate the process. Laravel uses composer as a dependency manager that manages all the information needed to manage packages. Packages are a great way to speed up development because they provide the functionality we need right out of the box.
4. Multiple File System
Laravel also has built-in support for cloud storage systems like Amazon S3, Rack space Cloud Storage, and local storage. Switching between these storage options is straightforward because each system's API remains the same. All three methods in one application can serve files from multiple locations, as in a distributed environment.
5. Engine Template
Laravel comes with a built-in template engine known as the Blade Template Engine. The Blade template engine combines one or more templates with a data model and creates the resulting views by translating the templates into cached PHP code for better performance. Blade also provides a set of control structures, such as conditional statements and loops, that are internally mapped to their PHP counterparts.
6. Task Scheduling
Introduced in Laravel 5.0, Scheduler is an addition to the Artisan command-line tool that allows programmatic scheduling of periodically executed jobs. Internally, the scheduler relies on the cron daemon to run a single Artisan job, performing the configured duties.
Regarding application testing, Laravel, by default, offers a unit test for the application, which contains tests to find and stop framework regressions. Integrating PHP units, such as the test framework, is straightforward in Laravel applications. Additionally, unit tests can be run through the provided artisan command line tool.
Future of Laravel Framework
PHP started as the first choice of web developers, but over the years, it has lost popularity to Python and Ruby on Rails. Their main drawback is the MVC implementation, which is aesthetically pleasing, while PHP is a reasonable choice for business owners with dramatic improvements in its latest versions. However, the challenge of finding the proper MVC framework ended when Laravel existed. Google Trends, leanpub.com, and various surveys have identified it as the best framework for PHP developers, which ensures a bright future for this framework.
Along with PHP development services, another trending domain is MVC development, a notable feature of modern websites. The Model View Controller framework is an application design pattern that separates the application data and logic model in two ways, increasing web page efficiency, performance, and speed. The PHP MVC framework provides access to standard libraries to avoid code repetition and comes with implemented database systems that reduce developer effort. Several extensions provide PHP MVC development services, significantly reducing time and cost. CWS is a software development company in Dubai that has built successful and effective websites for various brands for over a decade. CakePHP, Zend, Laravel, Yii, and CodeIgniter are trusted tools in the PHP MVC development arena, widely used worldwide for rapid web development.
All these predefined features of the Laravel framework are best suited for all kinds of web application development – from small to enterprise level. It also provides many built-in features that make it easy for developers to work. Additionally, the official packages provided by Laravel are the icing on the cake.
