Hello,
Currently, those are allowed:
new $classname;
classname::$methodname();
but those aren't:
$classname::foo();
$classname::CONST;
$classname::$member;
Here is a patch for head that fixes those inconsistencies by extending
the language parser to support such syntax:
http://patches.colder.ch/Zend/dynamic_static_calls.patch?markup (patch
also attached)
Regards
