Req #68475 [Com]: call_user_func($a) not equivalent to $a()

Edit report at https://bugs.php.net/bug.php?id=68475&edit=1 ID: 68475 Comment by: me at evertpot dot com Reported by: nicolas dot grekas+php at gmail dot com Summary: call_user_func($a) not equivalent to $a() Status: Assigned Type: Feature/Change Request Package: Scripting Engine problem PHP Version: 5.6.3 Assigned To: jpauli Block user comment: N Private report: N New Comment: Personally I think the major issue here is not so much that if call_user_func($a) is not equivalent to $a(), but rather that both is_callable and the callable typehint accepts a value that can't be invoked with $x(). Previous Comments: ------------------------------------------------------------------------ [2015-01-09 11:47:04] jpauli@php.net I don't think we need to RFC that. What we want, is uniformisation and consistency in the way we can call a PHP function from a PHP string. No new idea, no debatte, no RFC needed. ------------------------------------------------------------------------ [2015-01-08 20:16:32] aharvey@php.net I might prefer unifying the VM code with the code call_user_func() and friends use: something like https://github.com/LawnGnome/php-src/compare/call-static-methods?expand=1 (albeit I think we'd want to refactor the critical code path out of zend_is_callable_check_func() into a separate function to minimise the overhead). Having two sources of truth for what a string callable can look like is what got us in this mess. :) Whatever the approach, let's do this in PHP 7. Julien, do you want to write the RFC, or shall I? ------------------------------------------------------------------------ [2014-12-16 13:19:24] jpauli@php.net I agree that for consistency, this should be supported ------------------------------------------------------------------------ [2014-12-14 15:19:23] nicolas dot grekas+php at gmail dot com You can't say "just use the standard ['Class', 'method'] callback style"; there are of code out there that use the 'Class::method' style, you can't ignore it. This is where the blocker is: BC ------------------------------------------------------------------------ [2014-12-04 19:37:15] nikic@php.net I don't get why this is a blocker for anything. Why not just use the standard ['Class', 'method'] callback style? Imho the 'Class::method' style is just unnecessary duplication and should be removed in the future, rather than implemented in more places. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
