매개변수
- name
-
The name of the constant.
- value
-
The value of the constant; only scalar and null values are allowed. Scalar values are integer, float, string or boolean values.
- case_insensitive
-
If set to TRUE, the constant will be defined case-insensitive. The default behaviour is case-sensitive; i.e. CONSTANT and Constant represent different values.
