A post request arrives, how to read the body?

Question

PHP

A post request should arrive on the server, but I don’t know what it looks like, what body it has. Perhaps it is immediately in jsone, but perhaps not. How can I understand all this information and save it to textbook? PHP

Answer 1

var_dump(php://input);
And it’s better to check $_POST too, because:

php://input is not available with content type enctype="multipart/form-data".

Answer 2

var_dump($_REQUEST);
file_put_contents();
