HELP: SCA - migrating SQPaymentForm to Web Payments SDK - PHP

Yes. Your own examples.

When I worked on my own solution, and clearly the issues remain, your PHP examples are utter junk, missing large amounts of critical steps, along with sloppy code errors.

I mentioned this elsewhere (unsure if direct support, in a thread here, etc) 2 years ago. Clearly nothings been improved!!
