Yii2 development services: what makes the Yii2 framework special?

Programmers must make a choice that will underlie programming. Therefore, one of the biggest decisions you need to make as a programmer, but, most likely, you will make a decision as part of a team of programmers, whether or not to use the framework, and if so, which one.
As for the issue of using the PHP framework, there are so many benefits to use it.

Here are a few obvious advantages of using a Yii2 framework:

  • Uses standard ways of solving problems, which reduces or eliminates the intricacies of code.
  • Reduces the time spent on routine tasks, such as form validation and security.
  • Facilitates teamwork through compliance with standards.
  • Facilitates code support using common architecture and methods.
  • Has an active community of developers who support the framework, generalized tasks and new opportunities.

Flexibility and expandability

The Yii framework can be easily customized to suit your needs. Virtually every component of the framework is extensible.

Use of modern technologies

Yii is a fully object-oriented framework and takes full advantage of advanced PHP functions, such as the Standard PHP Library (SPL), Late Static Binding, and Anonymous Functions.

All classes are now in the same namespace, fully compatible with PSR-4.

Yii also allows you to specify aliases, which simplifies the use of namespaces.


Security is an essential part of any web application, and fortunately, in Yii there are great opportunities to facilitate the organization of protection.

Yii comes with a Security component that provides several methods to help you create a more secure application.

Some of the most useful methods are:

  • generatePasswordHash: This method generates a secure hash of the password and random salt. The method itself creates a random salt and then merges it with the password, then makes a hash through the crypt function of PHP.
  • validatePassword: This function is a relative of the generate PasswordHash function and allows you to check if the specified user password matches the one stored in the hash.
  • generate RandomKey: allows you to create a random string of any length.

Yii automatically checks the validity of the CSRF token on all unsafe HTTP request methods (PUT, POST, DELETE) and generates and displays a token when using the ActiveForm: begin () method to create its own form tag.
