You can get the value of a constant by simply specifying its name.
Unlike with variables, you should not prepend
a constant with a $.
- You can also use the constant-function, for
- example if the name of the constant is variable.
+ You can also use the function constant, to
+ read a constant's value, if you are to obtain the constant's name
+ dynamically.
Use get_defined_constants to get a list of
all defined constants.
