How do you ensure that there are no errors in your work?

To check for errors in PHP code, I use several approaches:

• Static code analysis with tools like PHPStan or Psalm, which help identify potential errors without running the program.
• Unit testing using PHPUnit to verify the logic of individual functions and classes.
• Logging and exception handling to catch and analyze errors during execution.
• Manual testing — checking functionality through a browser or API clients.
• Using a debugger (e.g., Xdebug) for step-by-step analysis of code execution.

This comprehensive approach helps minimize errors and improve code quality.
