Req #70508 [Com]: Support ::function similar to ::class

Edit report at https://bugs.php.net/bug.php?id=70508&edit=1 ID: 70508 Comment by: andreas at dqxtech dot net Reported by: andreas at dqxtech dot net Summary: Support ::function similar to ::class Status: Open Type: Feature/Change Request Package: PHP Language Specification Operating System: Linux PHP Version: 7.0.0RC2 Block user comment: N Private report: N New Comment: So far my workaround is: /* @see C::foo() */ $callback = 'C::foo'; This allows the IDE to "Find usages". But I need to manually check that the @see and the string are identical. Previous Comments: ------------------------------------------------------------------------ [2015-09-15 21:31:33] andreas at dqxtech dot net Description: ------------ Classes like ReflectionFunction, ReflectionMethod, or built-in functions like array_filter() accept functions identified as strings. This often leads to code like this, which is hard to analyse by the IDE: $callback = '\MyVendor\MyLibraray\MyClass::foo'; For classes, I already use the ::class language construct to make this understandable to the IDE, and allow things like "Find usages", or to let the IDE tell me that the class does not exist. I suggest to introduce a similar construct for functions and methods, ::function. Test script: --------------- class C { function fooMethod() {} } function fooFunction() {} print C::fooMethod::function . "\n"; print fooFunction::function . "\n"; Expected result: ---------------- C::fooMethod fooFunction Actual result: -------------- Fatal error: syntax error, unexpected T_DOUBLE_COLON ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70508&edit=1
