From: stealz at op dot pl Operating system: Windows 7 PHP version: 5.4.9 Package: Class/Object related Bug Type: Bug Bug description:Using twice the same trait causes fatal error.
Description: ------------ I think PHP should check whether traits were used already (ex. in parent class) and ignore them instead using again. It causes fatal error due to collisions which are obvious, because trait name is the same. What's interesting, collisions refer only to methods. PHP seems not to see the problem if double-used trait contains properties only. Test script: --------------- trait LifeOrganism { public $age; // it's fine #public function live() {} // uncomment to get Fatal error } trait Man { use LifeOrganism; } trait Elephant { use LifeOrganism; } class ElephantMan { use Man, Elephant; } Expected result: ---------------- Ignore trait which was already used. Actual result: -------------- Fatal error. -- Edit bug report at https://bugs.php.net/bug.php?id=63652&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63652&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63652&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63652&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63652&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63652&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63652&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63652&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63652&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63652&r=support Expected behavior: https://bugs.php.net/fix.php?id=63652&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63652&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63652&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63652&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63652&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63652&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63652&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63652&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63652&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63652&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63652&r=mysqlcfg
