Putting everything into $_POST isn’t a question of being RESTful or not. REST
in a
Web application happens at the HTTP protocol level and not the PHP level.
That said, it would be confusing to place the request body for all requests
into $_POST.
You also have to consider PATCH and the potential body for other HTTP methods.
The
easiest way to get the body of any HTTP request is to use the input stream:
$requestBody = file_get_contents('php://input');
I suppose we could make a super global that returns that for us, but it’s just
as easy to
use the above. Additionally, you might not want to put the full body of the
request into
memory like that. You might rather read the stream only a few bytes at a time.
