To PHPStan or not to PHPStan?

The pros and cons of using PHPStan for code quality analysis

PHPStan is a popular static analysis tool used for improving the quality of PHP code. It has several benefits as well as drawbacks that developers should consider before adopting it.


1. Early detection of errors

PHPStan is a static analysis tool that checks the code for errors and potential issues before it is executed. This means that developers can detect and fix errors early in the development process, reducing the likelihood of bugs appearing in production.

2. Improved code quality

PHPStan enforces strict typing and checks for unused code, unreachable code, and other issues that can affect the quality of the code. This helps developers to write more reliable and maintainable code, improving the overall quality of the project.

3. Easy to integrate with popular IDEs

PHPStan can be easily integrated with popular IDEs such as PhpStorm, VSCode, and Sublime Text, allowing developers to receive real-time feedback on potential issues as they write their code.


1. Steep learning curve

PHPStan has a steep learning curve, especially for developers who are new to static analysis. The tool requires a good understanding of PHP and type hinting, making it difficult for beginners to use.

2. High false-positive rate

PHPStan can produce a high number of false positives, especially when dealing with complex code. This can be frustrating for developers who have to spend time investigating issues that turn out to be false alarms.

3. Limited documentation

PHPStan has limited documentation, which can make it difficult for developers to understand how to use the tool correctly. This can lead to wasted time and frustration as developers try to figure out how to use the tool effectively.

In conclusion, PHPStan is a powerful tool for improving the quality of PHP code, but it has its pros and cons. Developers should carefully consider these factors before deciding to use the tool in their projects.
