5.4 Late static binding using "this" without "$" (or perhaps with a different name)
The same example, but now with the call to "self::static2()" replaced with "static::static2()", will then print "B::static2". Using static::func() is a bit corny, I understand why you don't want another new keyword so here is a few more suggestions: class::func() default::func() final::func() I personally think the class:: would be a better solution than static::, although this:: is the best solution, can I ask why that was ruled out since the title of the section indicates it was the first preference.
