define
Synopsis
bool define(stringname
, mixedvalue
[, intcase_insensitive
])
Defines a constant named name
and
sets its value to value
. If
case_insensitive
is set and is true
, the operation fails if a constant with
the same name, compared case insensitively, is previously defined.
Otherwise, the check for existing constants is done case sensitively.
Returns true
if the constant could
be created, or false
if a constant
with the given name already exists.
