Question
This class is Php programming
The sample code provided is a Song Organizer script that stores songs in a text file. Include functionality that allows users to view the song list and prevents the same song name from being entered twice. Also, included is code that will sorts the songs by name, deletes duplicate entries, and randomizes the song list with the shuffle() function.
Add detailed comments into the code ( // Comment or /* Comment */) explaining how the code works. Specifically, add comments to the code where comments are required.
Note: Please type up the whole PHP file, add in your comments and save the file as SongOrganizer.php. Upload SongOrganizer.php to the class web server in your module7a directory for grading.
