Is your goal to learn to program in PHP, and you're testing your knowledge on your website? Or, maybe you're looking for a quick form, with "point/click wizards" to help you get something up and running quickly? I used to be in a band, Ha!
If you really want to learn it, check YouTube for tutorials on “basic php mysql schedule”, or look for tutorials where you'll have to learn by not watching a video.
If you just want a quick bit of code to link to a database w/ HTML forms, you might try Googling keywords like "php mysql html form builder", etc.
Some of the older IDE's had some pretty nice HTML form builders. I think WeBuilder/ Rapid PHP (Blumentals software) has it, and their free trial gives you 30 runs (not 30 days. heck, i still have runs left on versions for the 2010's, but.. i'm abnormal)
