对高手来应该不算难!文章分类 及文章标题 分别为2个表中取出的数据
$cat = array(
        //  --------------------
array( "c" => "文章分类1",
              "list"  => array(
                  array("t" => "文章标题1"),
                  array("t" => "文章标题2"),
         array("t" => "文章标题3"),
         array("t" => "文章标题4"),
         array("t" => "文章标题5")
              )
          ),
         // ---------------------------
          array( "c" => "文章分类2",
              "list"  => array(
                  array("t" => "文章标题1"),
                  array("t" => "文章标题2"),
         array("t" => "文章标题3"),
         array("t" => "文章标题4"),
         array("t" => "文章标题5")
              )
          ),
          //------------------------
          array("c" => "文章分类3",
              "list"  => array(
                  array("t" => "文章标题1"),
                  array("t" => "文章标题2"),
         array("t" => "文章标题3"),
         array("t" => "文章标题4"),
         array("t" => "文章标题5")
              )
          )
          //------------------------
      );
