define
DEFINE(3) 1 DEFINE(3)define - Defines a named constantSYNOPSIS
bool define (string $name, mixed $value, [bool $case_insensitive = false])
DESCRIPTION
Defines a named constant at runtime.
PARAMETERS
o $name
- The name of the constant.
o $value
- The value of the constant; only scalar and null values are allowed. As of PHP 7 it also possible to use array value. Scalar val-
ues are integer, float, string or boolean values. It is possible to define resource constants, however it is not recommended and
may cause unpredictable behavior.
o $case_insensitive
- If set to TRUE, the constant will be defined case-insensitive. The default behavior is case-sensitive; i.e. CONSTANT and Con-
stant represent different values.
Note
Case-insensitive constants are stored as lower-case.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
