A few years back I had written a post about deciphering error messages, which still remains popular today. Because of the continued interest I have decided to update the original post and create a series on error reporting and handling in PHP.
When I first started learning about errors and error handling I found numerous tutorials on the topic, but none that provided a complete resource on the subject. This is understandable; since the topic is so broad one tutorial would not only be extremely long, it might also seem overwhelming to someone who just started learning about the topic. This is also the reason it would make a great topic to cover on a blog, where a series of posts can be created, each building on the information presented in the previous post ending with a comprehensive resource. (OK, comprehensive maybe a little strong but hopefully it will be close.)
The intended outline for the series is:
Resource Information
- Error Messages Deciphered (Revised)
- Error Reporting
- Displaying Errors
- Error Logging
- Backtrace Functions
- Triggering Errors
- Understanding Exceptions
Implementation
- Creating A Custom Error Handler
- Utilizing Exceptions
- Creating an Exception Hierarchy
Putting it all together
- Error Handling Strategies
