define

(PHP 3, PHP 4 >= 4.0.0)

define -- Defines a named constant.

Description

bool define ( string name, mixed value [, bool case_insensitive])

Defines a named constant. See the section on constants for more details.

The name of the constant is given by name; the value is given by value.

The optional third parameter case_insensitive is also available. If the value TRUE is given, then the constant will be defined case-insensitive. The default behaviour is case-sensitive; i.e. CONSTANT and Constant represent different values.

define() returns TRUE on success and FALSE if an error occurs.
