Join David Powers for an in-depth discussion in this video Building the web, part of Code Clinic: PHP.
- Hello, and welcome to Code Clinic. My name is David Powers. Code Clinic is a monthly course where a unique problem is introduced to a collection of lynda.com authors. In response, each author creates a solution using their programming language of choice. Mine is PHP. You can learn several things from Code Clinic: different approaches to solving a problem, the pros and cons of different languages, and some tips and tricks to incorporate into your own coding practices. This month, we're working on a problem common to anyone building a website or a report.
Specifically, merging live data with static templates. Data is only useful when we can effectively communicate it to someone else. And to do that, we need to format in some sort of meaningful visual representation. Sometimes this takes the form of a printed report. Most likely, it means publishing data to a web page. In this problem, we have the preformatted HTML web page and two data files in CSV format.
Our job is to write code that will insert the data files into the web page and apply the proper formatting. We're going to use the files created by James Williamson in Chapter 9 of his Dreamweaver CC Essential Training course. James provides all the material we need for this challenge. If you'd like to attempt your own solution, use the files from James' course. Alternatively, you'll find all you need in the exercise files for this month's Code Clinic. In the next videos, I'll show you how I solved this challenge.
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.
Q: I am unable to access the Lake Pend Oreille data from outside the U.S.
A: A static copy of this data is provided here for lynda.com members outside of the U.S
