Join David Powers for an in-depth discussion in this video Keeping the data up to date, part of Code Clinic: PHP.
…We've brought the database up to date manually, and as you…did so, you probably notice that some dates don't have any data.…For example in March 2014, there are two consecutive days we there is no data.…Doing the updates manually everyday would be tedious.…So once I've created a complete set of data locally, I…use phpMyAdmin to export it and to upload to my remote server.…If your not sure how to do that, take a look…at my course, Up and Running with phpMyAdmin here on lynda.com.…
And to do the daily updates, I adapted the…file that was used to get the individual files.…So let's go back to the editing program and see how to do that.…So this is the file that we're going to use, get_ individual_files.php.…Now we need to save that as get_PendOreille.php.…And…we can do some fairly rigorous surgery on this script.…We don't need to change the…max_execution_time; we can get rid of that.…We don't need to find out when we start or stop.…
So let's get rid of the start up there and then the end down here.…We do need to include the definition of the OneDay class and to import it.…
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-
