note 115616 added to language.oop5.inheritance

For multiple single inheretance to work the order of class definition is very important if you're going up more than two levels in inheretence. This won't work: <?php class A extends B {} class B extends C {} class C {} $A = new A; ?> Running the code above will spit a fatal error (Fatal Error:Class 'B' not found) A change in class definition order will fix this: <?php class A extends B {} class C {} class B extends C {} $A = new A; ?> If you're goin up just one level in inhertance though there shouldn't be any problem. So this code works too: <?php class A extends B {} class B {} $A = new A; ?> I have no explanation as to why this is the case though. ---- Server IP: 72.52.91.14 Probable Submitter: 41.99.77.249 ---- Manual Page -- http://php.net/manual/en/language.oop5.inheritance.php Edit -- https://master.php.net/note/edit/115616 Del: integrated -- https://master.php.net/note/delete/115616/integrated Del: useless -- https://master.php.net/note/delete/115616/useless Del: bad code -- https://master.php.net/note/delete/115616/bad+code Del: spam -- https://master.php.net/note/delete/115616/spam Del: non-english -- https://master.php.net/note/delete/115616/non-english Del: in docs -- https://master.php.net/note/delete/115616/in+docs Del: other reasons-- https://master.php.net/note/delete/115616 Reject -- https://master.php.net/note/reject/115616 Search -- https://master.php.net/manage/user-notes.php
