Parse errors are worse than fatal errors because they won t even let the script run at all; they merely give you the error information. Summary You have read through a lot of useful information in this chapter. Learning from your own mistakes and errors will help you to be quicker at noticing small, trivial mistakes that are causing problems in your code. The single best action a programmer can learn is how to troubleshoot. Once you have that figured out, nothing can hold you back from creating seamless applications that will impress you and your clients. Exercises Here are three short snippets of code to sift through. Try to spot the errors and figure out how to fix them. The answers are provided in Appendix A. Once you are finished, based on what you have learned, create a little error-catching script to catch the errors. 1. 2. 3. 272 Chapter 9
