From: Operating system: PHP version: 5.4.0alpha2 Package: Class/Object related Bug Type: Feature/Change Request Bug description:Traits vs Type hints
Description: ------------ Traits, when used in a class, are not added to class' type, and therefore can not be use in type hints. The RFCs on traits https://wiki.php.net/rfc/traits and on horizontal reuse https://wiki.php.net/rfc/horizontalreuse do not explain if this is by design. On the other hand Traits seem to share the same namespace as Classes and Interfaces, since it is impossible to have an Interface and a Trait that share the name ('Fatal error: Cannot redeclare class' is raised when this is attempted). Test script: --------------- <?php trait SomeTrait {} class SomeClass { use SomeTrait; } $a = new SomeClass(); var_dump(is_a($a,'SomeTrait')); Expected result: ---------------- bool(true) Actual result: -------------- bool(false) -- Edit bug report at https://bugs.php.net/bug.php?id=55266&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55266&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55266&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55266&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55266&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55266&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55266&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55266&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55266&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55266&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55266&r=support Expected behavior: https://bugs.php.net/fix.php?id=55266&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55266&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55266&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55266&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55266&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55266&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55266&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55266&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55266&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55266&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55266&r=mysqlcfg
