#36635 [NEW]: is_callable returns true for interfaces

From: slafontaine at avance dot info Operating system: Windows XP PHP version: 5.1.2 PHP Bug Type: Class/Object related Bug description: is_callable returns true for interfaces Description: ------------ When you use is_callable to check if a method is callable on an interface, it returns true which might be because Classes and Interfaces share the same namespace. Reproduce code: --------------- interface MyInterface { function callableFunc(); } if (is_callable(array("MyInterface", "callableFunc"))) { print("Is callable!"); call_user_func(array("MyInterface", "callableFunc")); } else { print("Is NOT callable!"); } Expected result: ---------------- Is NOT callable! Actual result: -------------- Is callable! Fatal error: Cannot call abstract method MyInterface::callableFunc() in path/to/file on line ### -- Edit bug report at http://bugs.php.net/?id=36635&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=36635&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=36635&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=36635&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=36635&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=36635&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=36635&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=36635&r=needscript Try newer version: http://bugs.php.net/fix.php?id=36635&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=36635&r=support Expected behavior: http://bugs.php.net/fix.php?id=36635&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=36635&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=36635&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=36635&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=36635&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=36635&r=dst IIS Stability: http://bugs.php.net/fix.php?id=36635&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=36635&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=36635&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=36635&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=36635&r=mysqlcfg
