What is Symfony? Familiarity with the popular PHP framework

PHP is one of the most important languages ​​for server-side programming, which is used by many programmers. This language has many frameworks and these frameworks provide many possibilities for programmers. In this article, we will talk about the symfony framework. What is Symfony and what are its uses?

What is the PHP programming language?

Implementing a site is divided into Front-End and Back-End sections. There are many technologies and languages ​​for implementing these sections. To implement Back-End we need server-side languages, PHP is one of the most popular languages ​​for server-side programming.

PHP is one of the best and most popular web programming languages ​​in the world. The simple and fluent PHP syntax makes learning this language sweet and enjoyable for you and it runs on different operating systems due to its multi-platform (Cross Platform).

PHP is mainly used in server-side programming of sites, but it is also used in other areas such as programming backends for mobile applications, building Rest APIs, and so on.

Today, about 70% of the world’s sites are implemented with PHP, and large sites such as Facebook, Wikipedia, etc. use this language. You can use these books to teach PHP and speed up the process of learning the popular PHP language.

What is the Symfony framework?

Frameworks are a set of frameworks and standards that accelerate the work of programmers in site and application development, and their use has many advantages in the project. Sites can work with Pure PHP or one of the language’s frameworks, depending on factors such as programmer skill and implementation complexity.

Symfony is a set of PHP components based on the MVC architecture and is the only framework that fully complies with PHP standards. Symfony is easy to install and configure on most platforms. And its best feature is the ability to reuse its PHP components.

The framework has a standalone database engine and is for fitting the best implementation methods and web design templates. Symfony lets you easily use other PHP libraries alongside it.

This framework has many user associations and is easier for professional and experienced developers to work with than other frameworks such as Laravel. These factors make Symfony the third most popular framework for developers after Laravel and Codeigniter.

What are the features of the Symfony framework?

This framework is one of the most reliable PHP language frameworks and a good option for implementing web applications. But why should we use symfony in our projects instead of frameworks like Laravel? It is better to take a look at the features of this framework.

High flexibility

Symfony has many features. The plugins of this framework, called bundles, are a collection of PHP files, images, JavaScript code, etc. that can be for implementing various parts of the site, such as blogs. Bundles are changeable and can be in other projects.

Symfony also has components that speed up the implementation of common parts of any project so that programmers can spend more time implementing more complex and custom parts.

The use of bundles and components helps to reduce project dependencies and make changes easier to implement, which makes Symfony highly flexible in web-based projects.

Test Acceptability

Using Design Patterns and bundles makes it very easy to test and control the code. Due to the use of PHPUnit library, unit testing and functional testing are also very simple.

Long-term support and active forums

Symfony has a lot of updates, and the previous versions are well compatible with the newer versions so that the developers do not have any problems. Also, having active communities and being open-source, this framework has made it easy for developers to modify it and make it available to other users for various uses.

What are the limitations of the Symfony framework?

Of course, there are reasons why Symfony loses first and second place and is happy with bronze. Symfony performance has always been about disscussing.

Symfony is less used in the implementation of social networks because it has little performance in real-time applications and is not able to respond to a large number of users simultaneously.

Of course, using PHP7 eliminates this weakness to some extent, but in some cases this limitation can be not important and programmers have to replace another framework.

As mentioned above, working with this framework is easier for experienced and professional people. Of course, Symfony features are worth learning. But if you want to start learning PHP, it is better to choose a simpler framework.


Frameworks are generally for simplifying the implementation process of a project. Although it may seem difficult to learn the powerful symfony framework. It does provide good features that may overlook its weaknesses.
