Bug #73105 [NEW]: ReflectionParameter returns nullable type when one is not used

From: mail at ciaranmcnulty dot com Operating system: OSX PHP version: 7.1.0RC2 Package: Class/Object related Bug Type: Bug Bug description:ReflectionParameter returns nullable type when one is not used Description: ------------ Reflection normalises typehints on parameters with defaults of null to be Nullable typehints. This is a change of behaviour and caused issues in Prophecy (Mocking library) and probably other tools that lean on reflection. It's not appropriate for a minor version number. Test script: --------------- function foo(Bar $bar = null){} echo ((new ReflectionFunction('foo'))->getParameters()[0]->getType()); Expected result: ---------------- output 'Bar' Actual result: -------------- output '?Bar' -- Edit bug report at https://bugs.php.net/bug.php?id=73105&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73105&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73105&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73105&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73105&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73105&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73105&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73105&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73105&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73105&r=support Expected behavior: https://bugs.php.net/fix.php?id=73105&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73105&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73105&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73105&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73105&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73105&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73105&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73105&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73105&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73105&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73105&r=mysqlcfg
