Thanks to SPL, it's also very easy to handle with PHP. This is courses.json, which is the common data directory. It contains exactly the same data as courses.xml except that it's in JSON format. So let's create a new PHP page to pass this data. And we're going to save it as json_decode.php. And we can load the data from the JSON file using file.getcontents. We'll save it as courses and we need to insert the path, which is common/data/courses.json. To convert the JSON into a format that PHP can handle, all that's necessary is to use the JSON decode function. We'll reassign it to courses. So json_decode, we pass it the raw JSON, which is stored as courses, and we can then inspect that using print_r.
