Module 4: Error Handling, Logging, and Debugging

  • Differentiating between various types of PHP errors: notices, warnings, and fatal errors
  • Configuring PHP error reporting levels for development and production environments
  • Implementing custom error handlers and robust exception handling mechanisms
  • Utilizing logging techniques for monitoring application behavior and issues
  • Introduction to common debugging tools and strategies for PHP applications

Module 5: Introduction to PHP Frameworks
