As the demands and complexity of Web applications continue to increase, choosing a suitable development framework has become increasingly important. Yii2 and CodeIgniter are both popular PHP frameworks, so which one is more suitable when building high-reliability web applications? This article will compare them and discuss their respective advantages and disadvantages.
First, let’s understand them. Yii2 is a new generation of excellent PHP framework with a large number of built-in advanced functions and tools, making development faster and easier. Yii2 also has complete caching support, automated testing, security and other features. CodeIgniter is a lightweight, efficient, fast and suitable PHP framework for small web applications. It helps developers build streamlined web applications faster, while CodeIgniter also focuses on performance and security.
Next, we will compare them in the following aspects:
- Community support: Yii2’s community is getting bigger and bigger, and more developers are sharing their experience and knowledge. At the same time, its community ecosystem has become more mature and stable. CodeIgniter is one of the most popular frameworks for PHP, with a large number of users and supporters. Although its community support is not as good as Yii2, in actual development, this may not be a fatal problem.
- Performance: Performance is one of the important features necessary for building web applications. For large-scale web applications, Yii2 is definitely more suitable than CodeIgniter. The performance of Yii2 is better, it can withstand more request traffic and higher concurrency. At the same time, Yii2's caching support is also very complete, which is very helpful for optimizing the performance of web applications.
- Security: When building web applications, you need to pay special attention to data security issues. Yii2 has many built-in security features such as input data validation, output filters, encryption and hashing, etc. By using these features, the data security of web applications can be more effectively protected. CodeIgniter's security is also excellent, including built-in security features for interacting with the database.
- Scalability: It is very important to build a scalable web application because the application will increase in reading volume and user size over time. In this regard, Yii2 is also a better choice. Yii2 can scale and adapt to web applications of all sizes and needs, and can also use third-party libraries and plug-ins.
In summary, Yii2 is a better choice for web applications with greater business needs. However, for small web applications, CodeIgniter is a better framework. It's reliable, high-performance, fast, and guaranteed to be reliable in every aspect. In the end, the choice between these two frameworks simply depends on your project needs and your development capabilities.

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
