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',
]
]
