Here are some bugfixing rules and tips I've learned working all these years with PHP. I emphasize mostly on fixing bugs than preventing them, which is another subject worth of its own article. I've moved to Rails, but I wanted to finish this post as a farewell and thanks to every article and documentation that was useful to me. Hope this is useful to you too.

Topics covered include:

• Assume nothing
• Turn Error Reporting to show all errors
• Read the error message
• Understand the bug
• "Scooby-Bug, where are you?"
• Get as much information as possible
