From: r dot van dot bezooijen at factua dot nl Operating system: Linux PHP version: 5.4.28 Package: Scripting Engine problem Bug Type: Bug Bug description:Interface inheritence not possible in interface Description: ------------ when overriding and interface method in another interface it's says they are incompatible with eachother while the overriding method contains a class/interface which is extended from the class/interface defined in the parent I think its also related to bug report 43200, Although it's not exactly the same problem. Test script: --------------- <?php interface IVisitee { public function accept( IVisitor $visitor ); } interface IVisitor { public function visit( IVisitee $visitee ); } interface IMetadata extends IVisitee { public function accept( IValidatorVisitor $visitor ); public function findConstraints( $group ); } interface IValidatorVisitor extends IVisitor { public function validate( $group, $transverse = false, $deep = false ); public function visit( IMetadata $visitee ); } Actual result: -------------- PHP Fatal error: Declaration of IMetadata::accept() must be compatible with IVisitee::accept(IVisitor $visitor) in /tmp/test.php on line 30 PHP Stack trace: PHP 1. {main}() /tmp/test.php:0 -- Edit bug report at https://bugs.php.net/bug.php?id=67232&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=67232&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=67232&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=67232&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=67232&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=67232&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=67232&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=67232&r=needscript Try newer version: https://bugs.php.net/fix.php?id=67232&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=67232&r=support Expected behavior: https://bugs.php.net/fix.php?id=67232&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=67232&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=67232&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=67232&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=67232&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=67232&r=dst IIS Stability: https://bugs.php.net/fix.php?id=67232&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=67232&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=67232&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=67232&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=67232&r=mysqlcfg
