Json数据，转换规则，

JSON数据转换，规则是遇见json 中的{},则是数组[],遇见name:value,则是‘key‘=>‘value‘, 但是不带键值的数组如[‘xxxxxx‘],json_encode后仍然是‘["xxxxx"]‘,若带键值，如[‘y‘=>‘xxxxxx‘],则会转换为{‘y‘:‘xxxxxxxx‘}这样的形式，完整例子，比如下面的可以相互转换,

{
   datas:[{stuid:"xxx",
      stuNo:"xxx",
      stuName:"xxx",
      completedSize:"xxx",
      uncompletedSize:"xxx"
      },
      {stuid:"xxx",
      stuNo:"xxx",
      stuName:"xxx",
      completedSize:"xxx",
      uncompletedSize:"xxx"
      }
   ],   
   page:{currpage:1,pageNo:"xxx",totals:"xxx"}
}

如果组织数据则是[

                         ‘datas‘=>[

                                        0=>[

                                                  ‘stuid‘=>‘xxxxx‘,

                                                  ‘stuNo‘=>‘xxxxxxxx‘,

                                                   ‘stuName‘=>‘xxxxxxxxxxxxx‘,

                                                   ‘completedSize=>‘xxxxxxxx‘,

                                                   ‘uncompleteSize‘=>‘xxxxxxxxxxxx‘,

                                             ],

                                          1=>[

                                                  ‘stuid‘=>‘xxxxx‘,

                                                  ‘stuNo‘=>‘xxxxxxxx‘,

                                                   ‘stuName‘=>‘xxxxxxxxxxxxx‘,

                                                   ‘completedSize=>‘xxxxxxxx‘,

                                                   ‘uncompleteSize‘=>‘xxxxxxxxxxxx‘,

                                             ]

                                         ]

                             ‘page‘=>[

                                                    currentPage=>‘1‘,

                                                    pageNo=>‘xxxx‘,

                                                    totals=>‘x‘,

                                          ]

                      ]
