Join David Powers for an in-depth discussion in this video Getting the most from Code Clinic, part of Code Clinic: PHP.
If you really want to get the most out of Code Clinic, try to create your own solution to the problem before you watch how I've done it. If you've spent time working on the question, you'll have a better idea of some of the difficult paths, and have a better understanding of why I've made certain choices. I've included the source code for my solution in the exercise files. I'm assuming you've already got the necessary tools installed to be able to edit and run the code. If not, I'd recommend you take a look at my introducing PHP course, here on lynda.com.
Code Clinic is a unique opportunity to look over my shoulder as I actually solve coding problems. Keep in mind that my solutions isn't the only correct solution. There are always a multitude of ways to solve a problem, but by watching how I approach the task, I hope you'll learn how to become a better programmer yourself.
David introduces challenges and provides an overview of his solutions in PHP. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
Visit other courses in the series to see how to solve the exact same challenges in languages like C#, C++, Java, Python, and Ruby.

Q: I'm encountering script errors message with the prime_dates.php file used in the "Priming the date_record column" movie in this course. How can I resolve these errors?

Line 9 of the prime_dates.php file. You can also download the latest
copy of the exercise files, which corrects this issue for you. For a
more in-depth explanation of the difference between bindValue() and
bindParam(), check out the "Binding input and output values" video (http://www.lynda.com/PHP-
