Testing it with a class called 'test' will issue a fatal error: undefined class constant 'c'. If the class 'test' already have a constant called 'c' define() will still ignore it and var_dump() will return the real value of test::c. ------------------------------------------------------------------------ [2008-04-25 10:01:38] kalle@php.net Description: ------------ PHP (5.2.5) allows you to define '::' as a constant without issuing an E_WARNING, below examples will demonstrate it. The constant() function will issue an fatal error when recieving '::' as constant name: Fatal error: Class '' not found in C:\webserver\www\gd\gd.php on line 91 Which might also be wrong or confusing to the programmer Reproduce code: --------------- <?php define('::', true); var_dump(constant('::')); ?> Expected result: ---------------- A fatal error for each of the calls: Fatal error: Invalid constant name in test.php on line 2 Fatal error: Invalid constant name in test.php on line 3 Actual result: -------------- Fatal error: Class '' not found in C:\webserver\www\gd\gd.php on line 91 None warning or fatal error for define()... ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44827&edit=1
