Join David Powers for an in-depth discussion in this video Overview of my solution, part of Code Clinic: PHP.
- Extracting data from a CSV file like this…and merging it into a webpage…is exactly the sort of task PHP was designed for.…The code for getting the data…from a CSV file is fairly elementary.…Your first instinct might be to embed it…directly into the webpage like this.…This script opens the file and then a while loop…uses the built in PHP function fgetcsv…that automatically converts the CSV into an array.…After that, it's just a matter of looping through the array…to display the results in the table.…
And if we load this page into a browser,…and then scroll down,…there's our table with all data in it.…The script works perfectly.…The problem with this approach is that…the code displays only one table…and we've got two CSV files.…So if you want to display both tables,…we'd have to repeat all of this code twice.…And what if a third CSV file is added?…Another problem is there's no fallback if the CSV file…can't be opened for any reason.…
I've come up with two alternative approaches.…One automatically generates an HTML table…
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-
