Why do we need anything more than HTTP GET, PUT, POST?

Question

What is the practical benefit of using HTTP GET, PUT, DELETE, POST, HEAD? Why not focus on their behavioral benefits (safety and idempotency), forgetting their names, and use GE

Answer 1

GET, PUT, DELETE and POST are holdovers from an era when sophomores thought that a web page could be reduced to a few hoighty-toity principles.

Nowadays, most web pages are composite entities, which contain some or all of these primitive operations. For instance, a page could have forms for viewing or updating customer information, which perhaps spans a number of tables.

I usually use $_REQUEST[] in php, not really caring how the information arrived. I would choose to use GET or PUT methods based on efficiency, not the underlying (multiple) paradigms.
