在Ruby中實現`call_user_func_array`

Question

如何在ruby中完成http://php.net/manual/en/function.call-user-func-array.php？

所以我可以這樣做：

class App 
    def foo(a,b) 
     puts a + b 
    end 
    def bar 
     args = [1,2] 
     App.send(:foo, args) # doesn't work 
     App.send(:foo, args[0], args[1]) # does work, but does not scale 
    end 
end 

Answer 1

嘗試爆炸刪除了`php`標籤陣列

App.send(:foo, *args)
