Schedule generator used to render and display my college class schedule.
It is currently running on https://www.cs.utexas.edu/~wang/schedule (as of 2019 - if you see this many years later, it might not be there anymore).
This was written in PHP because the UTCS web server uses a LAMP stack.
The actual code is located in schedule_generator.php. An example of how to interface with the schedule generator is located in demo.php. Essentially, just create an associated array as shown in demo.php and pass it in to the generate_schedule_table() function.
