define
(PHP 3, PHP 4 , PHP 5) define -- Defines a named constant
Descriptionbool 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.
Пример 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
