最近在開發(fā)微信平臺(tái)，要使用JSON進(jìn)行數(shù)據(jù)交換，之前用過(guò)JSON，但僅限于……在開發(fā)微信平臺(tái)中，要使用JSON形式如下：代碼片斷1：

 {     "button":[     {              "type":"click",          "name":"今日歌曲",          "key":"V1001_TODAY_MUSIC"      },      {           "type":"click",           "name":"歌手簡(jiǎn)介",           "key":"V1001_TODAY_SINGER"      },      {           "name":"菜單",           "sub_button":[           {                   "type":"view",               "name":"搜索",               "url":"http://www.soso.com/"            },            {               "type":"view",               "name":"視頻",               "url":"http://v.QQ.com/"            },            {               "type":"click",               "name":"贊一下我們",               "key":"V1001_GOOD"            }]       }] }

然后用php的json_encode()函數(shù)，對(duì)一二維數(shù)組轉(zhuǎn)換成JSON形式但轉(zhuǎn)換出來(lái)的JSON形式:代碼片斷2：

{    "button": {        "1": {            "type": "click",            "name": "今日歌曲",            "key": "V1001_TODAY_MUSIC"        },        "2": {            "type": "click",            "name": "歌手簡(jiǎn)介",            "key": "V1001_TODAY_SINGER"        },        "3": {            "name": "菜單",            "sub_button": [                {                    "type": "view",                    "name": "搜索",                    "url": "http://www.soso.com/"                },                {                    "type": "view",                    "name": "視頻",                    "url": "http://v.qq.com/"                },                {                    "type": "click",                    "name": "贊一下我們",                    "key": "V1001_GOOD"                }            ]        }    }}

看出來(lái)形式是不一致的。只能來(lái)了解一下JSON的結(jié)構(gòu)形式。JSON有兩種數(shù)據(jù)：1.無(wú)序的對(duì)象結(jié)構(gòu)；2.有序的數(shù)組結(jié)構(gòu)1.無(wú)序的對(duì)象結(jié)構(gòu)　無(wú)序的對(duì)象結(jié)構(gòu)在不同語(yǔ)言中稱法不同，比如在Python中稱為字典，在JS中稱為JSON對(duì)象……　總之就是鍵/值對(duì)組合形式。　剛才我轉(zhuǎn)換出來(lái)的JSON結(jié)構(gòu)就是無(wú)序的鍵/值對(duì)組合2.有序的數(shù)組結(jié)構(gòu)　有序的的數(shù)組結(jié)構(gòu)，即代碼片斷2所展示的結(jié)構(gòu)。　將數(shù)組作為有序數(shù)組進(jìn)行轉(zhuǎn)換JSON，就可以得到有序的JOSN數(shù)組結(jié)構(gòu)。
