Req #80327 [NEW]: Conflicts of parameter names and variadics

From: david at grudl dot com Operating system: PHP version: 8.0.0RC3 Package: Scripting Engine problem Bug Type: Feature/Change Request Bug description:Conflicts of parameter names and variadics Description: ------------ I quote directly from RFC: https://wiki.php.net/rfc/named_params > One of the primary use-cases for that variadic/unpacking syntaxes is forwarding of arguments. The support for named arguments in both variadics and argument unpacking ensures that this pattern will continue to work once named arguments are introduced. function passthru(callable $c, ...$args) { return $c(...$args); } Unfortunately, there is one limitation for forwarding at this time. You cannot pass argument with key 'c' to $args because it conflicts with parameter $c. So this passthru($callable, $args); May throws "Uncaught Error: Named parameter $c overwrites previous argument." depending on the content of (the otherwise valid) $args. How to solve it? A possible solution is to use a very non-conflicting name for $c, for example passthru(callable $██, ...$args), but I think that a better solution would be to ignore the conflicts if positional parameters are passed and variadics follows. -- Edit bug report at https://bugs.php.net/bug.php?id=80327&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=80327&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=80327&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=80327&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=80327&r=needscript Try newer version: https://bugs.php.net/fix.php?id=80327&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=80327&r=support Expected behavior: https://bugs.php.net/fix.php?id=80327&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=80327&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=80327&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=80327&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=80327&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=80327&r=dst IIS Stability: https://bugs.php.net/fix.php?id=80327&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=80327&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=80327&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=80327&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=80327&r=mysqlcfg
