A function (or "subroutine") is a generic term. A method is a function that belongs to a class.
sprintf and mysqli_query are functions, DateTime::add and mysqli::query are methods.

$abc; is not a declaration. PHP does not have those for regular global variables.
var $abc; declares a member variable of a class. It is a PHP 4 feature (see this) and was replaced with public in PHP 5.
