Get the Current Request Protocol

This is the defacto standard way to return the protocol of the current request.

PHP Code

function Request_Protocol() {
	/*
	Purpose
		Used to get the protocol used in the current request.
	Return (string)
		Returns "http" or "https" depending on the current protocol.
	Version History
		1.0 2016.06.23 Tested by Russ Tanner on PHP 5.3.10 and 5.6.1.
	*/

	return (
		( isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off' ) ||
		( isset($_SERVER['SERVER_PORT']) && $_SERVER['SERVER_PORT'] == '443' )
	) ? 'https' : 'http';
}
