What methods do you use to find and fix bugs in your code?

To find and fix errors in the code, I use the following methods:

• Logging: I add output of important variables and messages to the log to understand where the problem occurs.
• Debugger: I step through the code, tracking variable values and execution flow.
• Reading and analyzing code: I carefully check the logic, look for typos, incorrect conditions, or function calls.
• Unit tests: I write tests that help identify errors in individual parts of the code.
• Using built-in error handling functions: For example, in PHP — functions like error_reporting(), var_dump(), print_r().

Example of using a debugger in PHP with Xdebug:

// Run the script with Xdebug enabled and set a breakpoint
// In IDE, you can step through the code and check variable values
