note 102199 added to language.oop5.constants

Summary: use ReflectionObject to access class const in PHP older than 5.3. In versions <= 5.2 you can't use the $object::constMember syntax. Accessing via class name or the `self' operator doesn't resolve the right class in case of inheritance (for the C++ folks, it behaves like a NON-virtual method). The only working (if ugly) solution to access seems to be to use the Reflection extension: <?php class Foo { const a = 7; const x = 99; } class Bar extends Foo { const a = 42; /* overrides the `a = 7' in base class */ } $b = new Bar(); $r = new ReflectionObject($b); echo $r->getConstant('a'); # prints `42' from the Bar class echo "\n"; echo $r->getConstant('x'); # prints `99' inherited from the Foo class ?> ---- Server IP: 69.147.83.197 Probable Submitter: 89.228.5.182 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.constants.php Edit -- https://master.php.net/note/edit/102199 Del: integrated -- https://master.php.net/note/delete/102199/integrated Del: useless -- https://master.php.net/note/delete/102199/useless Del: bad code -- https://master.php.net/note/delete/102199/bad+code Del: spam -- https://master.php.net/note/delete/102199/spam Del: non-english -- https://master.php.net/note/delete/102199/non-english Del: in docs -- https://master.php.net/note/delete/102199/in+docs Del: other reasons-- https://master.php.net/note/delete/102199 Reject -- https://master.php.net/note/reject/102199 Search -- https://master.php.net/manage/user-notes.php
