8 Cons of Yii

• Steep Learning Curve: While Yii is relatively easy to learn compared to some other frameworks, it still has a learning curve, especially for novice developers. It may take some time to master all its features and concepts.
• Less Popular Compared to Some Other Frameworks: Yii, although popular, is not as widely used as some other frameworks like Laravel or Symfony. This may result in a smaller pool of developers with Yii expertise.
• Less Flexibility: Yii follows a structured and opinionated approach, which may limit the flexibility for developers who prefer more freedom in coding and architecture decisions.
• Less Documentation for Advanced Topics: While Yii has comprehensive documentation, some advanced topics may have limited documentation available. Developers may need to rely on community forums or external resources to find solutions to specific advanced issues.
• Less Support for Third-Party Integrations: Although Yii provides a wide range of built-in features and extensions, it may have less support for certain third-party integrations compared to some other frameworks.
• Less Suitable for Small Projects: Due to its feature-rich nature, Yii may not be the most suitable choice for small projects or simple websites where a lightweight framework would suffice.
• Less Intuitive Configuration: Yii’s configuration can sometimes be complex and less intuitive, especially for beginners. It may require some effort to understand and set up the configuration properly.
• Limited Official Learning Resources: While Yii has good documentation, it may have limited official learning resources like video tutorials or online courses compared to some other frameworks.

Cases when Yii does not work

1. Yii does not work when the server does not meet the minimum system requirements. Yii requires PHP 5.4 or higher and various PHP extensions, such as PDO, MBstring, and GD. If these requirements are not met, Yii may not function properly.
2. Yii may not work if the server’s file permissions are not set correctly. Yii requires certain directories to be writable by the web server, such as the runtime and assets directories. If the permissions are not set correctly, Yii may encounter issues when trying to write or access these directories.
3. Yii may not work if there are conflicts with other software or libraries installed on the server. Incompatibilities between different versions of PHP, web servers, or other software can cause Yii to malfunction or produce errors.
4. Yii may not work if the application code contains errors or conflicts with the framework. Incorrectly written code, such as syntax errors or improper use of Yii’s features, can lead to unexpected behavior or crashes.
5. Yii may not work if the database configuration is incorrect or if there are connectivity issues with the database server. Yii relies on a database to store and retrieve data, so any problems with the database configuration or connectivity can prevent Yii from functioning properly.
6. Yii may not work if the server experiences performance or resource limitations. If the server is under heavy load or lacks sufficient resources, such as CPU or memory, Yii’s performance may be affected, resulting in slow response times or even crashes.
7. Yii may not work if there are compatibility issues with certain web browsers or client devices. While Yii is designed to be compatible with various browsers and devices, there may be instances where specific features or functionalities do not work as expected on certain platforms.
