Answer 1

It gives you direct access to the input stream, as opposed to accessing the data after PHP has already applied the $_GET/$_POST super globals. Also, according to the manual, it is both less intensive and allows you to grab information before any php.ini directives have been applied.

php:// is a scheme wrapper around various input/output streams that PHP supports. You can read up for here: http://www.php.net/manual/en/wrappers.php.php.

Specifically, php://input allows you to read the input stream directly.
