Yii2 Developers

Yii2 Developers for Hire

Many online projects still rely on raw PHP and PHP frameworks for their backend. Companies hire PHP experts for various jobs due to the language’s technological capabilities. Though other technologies are gaining popularity, back-end coding remains a competitive field. 

PHP offers various frameworks, including Yii, which is a popular choice for applications of all sizes. This article aims to help startup owners incorporate Yii2 developers into their businesses and guide them on how and where to hire Yii2 developers.

Definition of Yii2 Framework

Yii 2 (meaning simple and evolutionary in Chinese) is a contemporary framework that offers a stable foundation for your PHP application. If you’re looking for a way to streamline your development process, Yii2 is an excellent choice. It includes a CRUD-generating module called Gii that enables you to quickly produce a significant amount of common code.

Yii2 is a fast, secure, and efficient framework with sensible defaults that are pre-configured. Because Yii2 is designed to be flexible, it’s easy to modify the framework to suit your needs.

Technologies Used in Yii2 Framework Development

  1. Installation:

    The Yii2 Framework can be installed in two ways: either by using a composer and running a single command, or by downloading an archive from the internet. Upon installation, Yii provides a straightforward template for a web application.
  2. Template System:


    Unlike other PHP frameworks, Yii2 doesn’t come with a built-in templating mechanism. It allows developers to use their own judgment in selecting a system that is best suited to their tasks. Two of the most popular alternatives are Smarty and Twig.
  3. Database:


    Yii2 has robust support for databases, particularly for relational database management systems such as Oracle, SQLite, PostgreSQL, and MySQL, and comes with built-in support for ActiveRecord ORM. Additionally, third-party packages for Microsoft Business Intelligence and MongoDB are available.

API Support: 

Like most of the modern PHP frameworks, Yii is designed to handle API routes, JSON, and oAuth 2 data inputs. However, this is an optional feature that can be disabled if not needed.

Benefits of Using the Yii Framework in Development Industry

  1. Reduced Development Time:


    Yii offers a variety of tools for automating repetitive tasks in projects, which can significantly reduce development time. This allows developers to focus their time and attention on critical business needs and logic. One such tool is “Gii,” which automates the process of creating code templates for Models, Controllers, Forms, Modules, and Extensions. Gii is highly customizable, providing developers with complete freedom to create scalable and personalized code.
  2. Security:


    Yii comes with several security features, including anti-XSS, anti-Cross Site Scripting, and anti-CSRF (Cross-Site Request Forgery) measures. Yii addresses the three most significant security concerns in the following ways:
    • In situations where a web application acquires information from users, such as on a forum, there is a risk that malicious code could be included in the posts. Yii offers a highly beneficial component called CHtmlPurifier, which eliminates potentially hazardous content and ensures that filtered content meets industry standards.
    • Yii has built-in CSRF (Cross-Site Request Forgery) validation by default. CSRF prevention occurs when a malicious website directs a user’s browser to perform an unwanted action on a trusted site. Yii includes a CSRF protection mechanism to assist in blocking POST-based attacks.
    • Yii offers a cookie validation mechanism that prevents cookies from being altered. It performs an HMAC (Hash-based message authentication code) check on enabled cookie values.
  3. Caching:


    Being a highly effective technique for enhancing the speed of a web application, caching leads to a reduction in response time and improves the overall speed and performance of the web application. Yii simplifies the process of integrating a cache application component. Yii features a variety of cache components, such as:
    • cMemCache:

       Memcache uses RAM from multiple servers to function as a memory cache for frequently requested data.
    • cDummyCache:

       This section contains a dummy cache that does not perform any caching. This component is designed to simplify the code responsible for checking the cache’s availability.
    • cFileCache:

       This class stores cached data in files.
  4. Simple Configuration:


    Yii’s installation process is straightforward. The basic framework can be obtained from the Yii framework website or using composer. After downloading the structure and extracting its contents, developers only need to link the files to the database and provide the database configuration included in the configuration file, and the database becomes operational.
    • Yii provides an object-oriented, open-source programming language along with streamlined security.
    • CRUD (Create, Read, Update, and Delete) generators and the MVC (Model-View-Controller) architecture.
    • By default, Yii utilizes the latest static binding along with anonymous functions.
    • CodeIgniter integration makes it easy to conduct functional and unit tests.
    • The development process is accelerated with an abundance of readily available solutions and extensions.
    • Yii is a well-documented framework with a strong and supportive community, making it scalable for various applications.
  5. Extensive community support:


    Yii boasts a massive community of developers that provides forums, discussion groups, live chat, news, and even a hall of fame. Additionally, developers can earn badges for meeting specific requirements outlined in the Yii framework community. Yii offers limitless support through various plugins and components.

Costs of Yii Development

Yii development costs vary by location and type of employment, with rates ranging from $14 to $32 per hour for mid-level developers. Unlike other PHP frameworks, Yii does not come with predetermined hosting and deployment platforms, so expenses will vary based on the pricing range of cloud or custom servers. Additional expenses to consider include research and ongoing maintenance costs.

Yii2 Developer Demand

Yii web development offers a substantial amount of projects, leading to a high demand for Yii developers. Companies seeking Yii developers typically need assistance building complex large-scale systems from scratch or maintaining existing projects. If you are looking to hire Yii developers, you can expect to find a healthy demand in the industry.
