Bug #78897 [NEW]: ReflectionMethod::getClosure declaration changed silently in 7.4

From: dinchev dot dimitar at gmail dot com Operating system: Linux PHP version: 7.4.0 Package: Reflection related Bug Type: Bug Bug description:ReflectionMethod::getClosure declaration changed silently in 7.4 Description: ------------ Since upgrading to PHP 7.4, I get the following PHP Warning: Declaration of Go\ParserReflection\ReflectionMethod::getClosure($object) should be compatible with ReflectionMethod::getClosure($object = NULL) The above framework class is extending ReflectionMethod and until 7.3.x the declaration of ReflectionMethod::getClosure($object) apparently didn't have default null value, now making it incompatible with the subclass declaration. The change is not reflected in the release notes of PHP 7.4.0 or in the current documentation: https://www.php.net/manual/en/reflectionmethod.getclosure.php Test script: --------------- <?php class ReflectionMethodSubclass extends ReflectionMethod { public function getClosure($object) { return parent::getClosure($object); } } -- Edit bug report at https://bugs.php.net/bug.php?id=78897&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=78897&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=78897&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=78897&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=78897&r=needscript Try newer version: https://bugs.php.net/fix.php?id=78897&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=78897&r=support Expected behavior: https://bugs.php.net/fix.php?id=78897&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=78897&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=78897&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=78897&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=78897&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=78897&r=dst IIS Stability: https://bugs.php.net/fix.php?id=78897&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=78897&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=78897&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=78897&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=78897&r=mysqlcfg
