Edit report at https://bugs.php.net/bug.php?id=72344&edit=1 ID: 72344 Updated by: stas@php.net Reported by: chad dot sikorra at gmail dot com Summary: Allow the Splat Operator with InstanceOf -Status: Open +Status: Suspended Type: Feature/Change Request Package: *General Issues Operating System: Irrelevant PHP Version: 7.0.7 Block user comment: N Private report: N New Comment: Thank you for your interest in PHP and for submitting a feature request. Please be aware that due to the magnitude of change this request requires, it would be necessary to discuss it on PHP Internals list (internals@lists.php.net) as an RFC. Please read the guide about creating RFCs here: https://wiki.php.net/rfc/howto If you haven't had experience with writing RFCs before, it is advised to seek guidance on the Internals list (http://php.net/mailing-lists.php) and/or solicit help from one of the experienced developers. Please to not consider this comment as a negative view on the merits of your proposal - every proposal which requires changes of certain magnitude, even the very successful and widely supported ones, must be done through the RFC process. This helps make the process predictable, transparent and accessible to all developers.

I'm not sure if this is practical/possible to implement, but it would be very useful to use that same sort of type checking with the splat operator for instanceof checks, such as: if (...$dates instanceof \DateTime). Currently that syntax produces "PHP Parse error: syntax error, unexpected '...' (T_ELLIPSIS)". Test script: --------------- $foo = [ new \DateTime(), new \DateTime()]; if (...$foo instanceof \DateTime) { echo "DateTime"; } Expected result: ---------------- DateTime Actual result: -------------- PHP Parse error: syntax error, unexpected '...' (T_ELLIPSIS) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72344&edit=1
