Join David Powers for an in-depth discussion in this video Overview of my solution, part of Code Clinic: PHP.
This month's challenge…is to control sound with the mouse.…PHP is my chosen programming language…for Code Clinic.…The big question is whether this is…the sort of project PHP can handle.…Let's consider some possible approaches.…If you search the PHP documentation,…you'll find there's a function called…ncurses_getmouse, that's designed…to get mouse coordinates.…There's also an ogg://wrapper…that can be used to stream sound.…So, it might be possible to devise a way…to use the output of ncurses_getmouse…to control the audio stream.…
It might, but there are formidable obstacles.…The Ncurses extension was removed from PHP 5.3.…It's still available as a pickle extension,…but the PHP documentation describes it as being…of little use for writing web applications.…The ogg audio wrapper is also non-standard,…but perhaps the biggest obstacle…is that PHP is a server-side language.…Although it's common to have…a local server for testing,…PHP is primarily intended to serve data over…the internet or a network from a remote server.…
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-
