Req #51381 [NEW]: Clarify class definition order importance for multiple levels of inheritance

From: Operating system: PHP version: 5.2.13 Package: Documentation problem Bug Type: Feature/Change Request Bug description:Clarify class definition order importance for multiple levels of inheritance Description: ------------ It is not clear from the PHP5 class documentation how important the order of class definition is in the the context of multiple levels of inheritance. According to the PHP4 doc on extends @ http://php.net/manual/en/keyword.extends.php the following code is incorrect due to the order in which the classes are defined: class one extends two {} class two extends three {} class three {} However PHP5's docs make no mention if the order of definition is still significant. OR if its only significant when there are multiple levels of inheritance. The preceding code throws a fatal error 'class not found' for the class two. The following code however does work: class one extends two {} class two {} Request clarification please. -- Edit bug report at http://bugs.php.net/bug.php?id=51381&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=51381&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=51381&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=51381&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=51381&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=51381&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=51381&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=51381&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=51381&r=needscript Try newer version: http://bugs.php.net/fix.php?id=51381&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=51381&r=support Expected behavior: http://bugs.php.net/fix.php?id=51381&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=51381&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=51381&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=51381&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=51381&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=51381&r=dst IIS Stability: http://bugs.php.net/fix.php?id=51381&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=51381&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=51381&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=51381&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=51381&r=mysqlcfg
