From: kotlyar dot maksim at gmail dot com Operating system: linux PHP version: 5.4.10 Package: Scripting Engine problem Bug Type: Bug Bug description:implementation child interface and after parent cause fatal error.
Description: ------------ Order of implemented interfaces should make any difference. But it is not the case. If I implement child interface and parent after I will get a fatal error Test script: --------------- <?php ini_set('display_errors', 1); error_reporting(-1); interface RootInterface { function foo(); } interface FirstChildInterface extends RootInterface { function foo(); } interface SecondChildInterface extends RootInterface { function foo(); } //works fine. class A implements FirstChildInterface, SecondChildInterface { function foo() { } } //also ok. class B implements RootInterface, FirstChildInterface { function foo() { } } //there is a fatal error. class C implements FirstChildInterface, RootInterface { function foo() { } } Expected result: ---------------- Should work without errors(as previous examples). Actual result: -------------- PHP Fatal error: Class C cannot implement previously implemented interface RootInterface in /foo/test.php on line 35 PHP Stack trace: PHP 1. {main}() /foo/test.php:0 Fatal error: Class C cannot implement previously implemented interface RootInterface in /foo/test.php on line 35 Call Stack: 0.0008 238784 1. {main}() /foo/test.php:0 -- Edit bug report at https://bugs.php.net/bug.php?id=63816&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63816&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63816&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63816&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63816&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63816&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63816&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63816&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63816&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63816&r=support Expected behavior: https://bugs.php.net/fix.php?id=63816&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63816&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63816&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63816&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63816&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63816&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63816&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63816&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63816&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63816&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63816&r=mysqlcfg
