Join David Powers for an in-depth discussion in this video Setting up the database, part of Code Clinic: PHP.
…Before diving into the PHP side of this project, let's take a…look at how the raw data will be stored in a database.…I'm using MySQL and phpMyAdmin, but you can use the database of your choice.…Instead of going through the database setup step by…step, I'll focus on the decisions I made and why.…By the way, if you need help with…creating database tables and user accounts in MySQL,…take a look a my course, Up and…Running with phpMyAdmin in the lynda.com online training library.…
I decided to create a separate database called pendoreille.…So let's take a look at that by clicking the pendoreille link on the left here.…And it contains two tables.…The first table, environmental data, contains…the measurements from 2001 to early 2014.…The second one, serialized data, only goes up to May 2010 and…if I zoom in a little and if we look at the size over here on the right…hand side, you can see why I abandoned the serialized data table.…
Although it contains less data, it's nearly…four times the size of the other 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?

bindParam(), check out the "Binding input and output values" video (http://www.lynda.com/PHP-
