array(9) {
   ["id"]=>  
  string(1) "1"
  ["radioname"]=>
  string(1) "小二"
  ["author"]=>
  string(9) "小三"
   ["did"]=>
  string(1) "1"

对,是这样的
传入的数据都是字符型的
但这并不影响数据的使用

查出来的数据用做java的接口,他们要求给数字类型,如果没办法,只能查出来之后用intval()转一下

再怎么变,传到java时也还是串

啊,那客户端的同学让我给int,欺负姐不懂科学

很简单,你说让他 post 个 int 给你才能返回 int 给他

额,是我没描述好,查出来要生成json
"id":"1"
"id":1
客户java解析的办法就不一样了吧

都是一样的,JSON的标准格式是键名和值都以双引号括起的

你自己看一下 json_encode 函数的结果就清楚了
