Req #62325 [Com]: Debug Backtrace gives no handle to anonymous functions

Edit report at https://bugs.php.net/bug.php?id=62325&edit=1 ID: 62325 Comment by: anfurny22 at gmail dot com Reported by: anfurny22 at gmail dot com Summary: Debug Backtrace gives no handle to anonymous functions Status: Open Type: Feature/Change Request Package: *General Issues Operating System: Windows PHP Version: 5.4.4 Block user comment: N Private report: N New Comment: I agree the key name is ambiguous, perhaps 'function_reference' instead of 'reference'. I'm unclear what you're saying about "returning" a reflection object, please elaborate. Previous Comments: ------------------------------------------------------------------------ [2012-06-17 11:01:14] hanskrentel at yahoo dot de I think the naming can be improved. Reference is quite generic, why not to return some reflection object if asked for? ------------------------------------------------------------------------ [2012-06-14 17:25:19] anfurny22 at gmail dot com Description: ------------ Debug backtrace traditionally gives several pieces of information about the call stack, including file name, line number, and function name. However, with anonymous functions it simply gives "{closure}". This makes anonymous functions received through debug_backtrace inaccesible through reflection because there is no reference to them. I propose that debug_backtrace always provide an additional key "reference" which is a reference to the actual function. This will let the function be called or provided to the reflection API. Test script: --------------- <?PHP $anon = function() { $name = (debug_backtrace[0]['name']); // yields {closure} $refl = new ReflectionFunction($name); // works great except with closures! echo $refl->getDocComment(); // fails } $anon(); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62325&edit=1
