关于利用json实现java与php间的传值机制有关问题
关于利用json实现java与php间的传值机制问题！
我现在遇到这样一个问题：
首先以下这一步我可以实现，就是java程序向我的php页面发出请求，我用json_encode把要反馈的数据返回给java程序那边
然后现在以下这一步我不知道怎么实现，不知道里面的机制该怎样去实现？！！！
就是java程序给我的php页面发json数据包，那我该用php的什么函数或者用自定义一个怎样的方法去获取java程序发过来的json数据包呢？用request行不行？
只要我知道如何获取得了，那么我就知道如何去解释它的json数据包了~~
求高手~~感激不尽来了~
小的我分数不是很多，这能尽量给这么多了~~
