Join David Powers for an in-depth discussion in this video Using the exercise files, part of Code Clinic: PHP.
If you're a subscriber to the lynda.com online training library, you can download the exercise files for code clinic. I've got them here on my desktop, so if I open that folder, inside there is a folder for problem one, and inside problem one are separate folders to accompany each video. Each of these folders contains all the files that you need for that video. If I open one of them, there are three files in here. The first one, process_years.php, is the file that you'll need at the beginning of the video.
But when changes are made to a file during the video, a second version with end appended to the name, shows what it will look like at the end of the video. Sometimes, to save time, I provide snippets of code in text files for you to copy and paste into your working file. Because PHP code needs to be parsed by a web server, you'll need to copy the files into the root folder of a PHP enabled server. I'm using, a local-testing server. And I've created a folder called, phpclinic, inside the server root.
So, let's go and have a look at phpclinic and inside there, I'll create a separate folder for each problem. So, here is problem one. And I've created all of the files in the root of that folder. Occasionally, the exercise files will contain everything you need to follow along. For example, in problem one, you need to download the contents of the raw data folder directly from an external website. But that's the exception rather than the rule. And if you need help setting up a PHP testing environment, check out David Gassner's course, Installing Apache, MySQL, and PHP, here in the lynda.com online training library.
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?
A: To avoid script errors, use bindValue() instead of bindParam() in
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-
Q: Why can't I access the Lake Pend Orielle site (http://lpo.dt.navy.mil)?
A: The Lake Pend Orielle site is not accessible in some geographical areas. We have contacted the owner of the server to try to resolve this issue.

A: A static copy of this data is provided here for lynda.com members outside of the U.S
