[Difficult] the array of the smarty template seems to be completely equivalent. why? $ Arr = array (& quot; a & quot; = & gt; array (1, 2, 3), & quot; B & quot; = & gt; array (& quot; c & quot; = & gt; array (& [difficult] the array of the smarty template seems completely equivalent. why?
$ Arr = array ("a" => array (1, 2, 3 ), "B" => array ("c" => array ("d" => array ("e" => "Tom ", "f" => "BeiJing "))));
$ Smarty-> assign ("A", $ arr );
$ Smarty-> display ("testTwo.html ");


HTML code
