Bug #53683 [NEW]: Presence of __invoke makes protected __construct visible as callable

From: Operating system: Irrelevant PHP version: 5.3.5 Package: *General Issues Bug Type: Bug Bug description:Presence of __invoke makes protected __construct visible as callable Description: ------------ Presence of __invoke causes is_callable($obj, '__construct') returns true, instead of false when it's called out of class scope. Also, is_callable('class', '__construct') yields true even if __construct is set to protected (which is clearly not connected with __invoke issue, but I suppose that is caused by the same underlying problem). Although setting __construct private/protected seems a little bit pervert, if it is not interdicted by language semantics, visibility testing should give good results. Test script: --------------- class Singleton { protected static $aInstances = array(); final protected function __construct(){} public static function getInstance(){ $sClassName = get_called_class(); if (!isset(static::$aInstances[$sClassName])) { static::$aInstances[$sClassName] = new $sClassName(); } // if return static::$aInstances[$sClassName]; } // getInstance } // class class SingletonWithInvoke extends Singleton { final protected function __invoke(){} } // class var_dump(is_callable(Singleton::getInstance(), '__construct')); var_dump(is_callable(SingletonWithInvoke::getInstance(), '__construct')); var_dump(is_callable('Singleton', '__construct')); var_dump(is_callable('SingletonWithInvoke', '__construct')); Expected result: ---------------- bool(false) bool(false) bool(false) bool(false) Actual result: -------------- bool(false) bool(true) bool(true) bool(true) -- Edit bug report at http://bugs.php.net/bug.php?id=53683&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=53683&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=53683&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=53683&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=53683&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=53683&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=53683&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=53683&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=53683&r=needscript Try newer version: http://bugs.php.net/fix.php?id=53683&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=53683&r=support Expected behavior: http://bugs.php.net/fix.php?id=53683&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=53683&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=53683&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=53683&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=53683&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=53683&r=dst IIS Stability: http://bugs.php.net/fix.php?id=53683&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=53683&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=53683&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=53683&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=53683&r=mysqlcfg
