Join David Powers for an in-depth discussion in this video Reorganizing the folder structure, part of Code Clinic: PHP.
- We've got two arrays.…One of images, the other of captions.…To reorganize the directory structure,…we need to sort the captions array alphabetically…without losing the relationship…with the correct images.…We can do that using the array_multisort function.…The first argument to array_multisort…is the array you want to sort first.…On line 20, we can get rid of this print_r…and we'll use array_multisort.…
The first one is the captions array…and the second argument is how you want…to sort the array.…We want to sort it in a case insensitive manner.…We need to use a couple of PHP constants.…The first one is sort string,…sort_string…and then separate that by a vertical pipe…and sort flag case,…so sort_flag_case.…
That's a case insensitive sort in array_multisort.…Then the last argument is the other array…that we want to sort which is called files.…This will sort our captions in ascending alphabetical order…and it will keep the correct files in the same order.…Let's display the results.…I'm going to use an HTML definition list…
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-
