+ | The same ambiguity that exists between static methods and namespaced functions also exists between class constants and namespaced constants. | ||
+ | From the users point of view it not possible to determine, with any easy or certainty, from the code whether **TEST:: | ||
+ | |||
+ | class.inc: | ||
+ | <code php> | ||
+ | <?php | ||
+ | class TEST { | ||
+ | const MY_CNST_ONE = 'TEST class CONSTANT ONE'; | ||

+ | output of example1.php (regardless of include order): | ||
+ | < | ||
+ | TEST namespace CONSTANT ONE | ||
+ | TEST class CONSTANT TWO | ||
+ | </ | ||
+ | |||
+ | There is no way to reference the constant **MY_CNST_ONE** from class **TEST**, additionally because constant **MY_CNST_TWO** from class **TEST** is reachable one is left with the potential that the namespaced include will break current code if a constant **MY_CNST_TWO** is later defined in the TEST namespace, regardless it introduces confusion because one is it possible to retrieve constants from two different ' | ||
