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

From: andreas at dqxtech dot net Operating system: Linux PHP version: 7.0.0RC2 Package: PHP Language Specification Bug Type: Feature/Change Request Bug description:Support ::function similar to ::class 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 bug report at https://bugs.php.net/bug.php?id=70508&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=70508&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=70508&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=70508&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=70508&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=70508&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=70508&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=70508&r=needscript Try newer version: https://bugs.php.net/fix.php?id=70508&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=70508&r=support Expected behavior: https://bugs.php.net/fix.php?id=70508&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=70508&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=70508&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=70508&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=70508&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=70508&r=dst IIS Stability: https://bugs.php.net/fix.php?id=70508&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=70508&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=70508&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=70508&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=70508&r=mysqlcfg
