                                    define

   (PHP 3, PHP 4 )
   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.

   Example 1. Defining Constants
   <?php
   define("CONSTANT", "Hello world.");
   echo CONSTANT; // outputs "Hello world."
   echo Constant; // outputs "Constant" and issues a notice.
   define("GREETING", "Hello you.", true);
   echo GREETING; // outputs "Hello you."
   echo Greeting; // outputs "Hello you."
   ?>

   Returns TRUE on success or FALSE on failure.

   See also defined(), constant() and the section on Constants.
