在php中检索JSON表单数据

Question

我有一个HTML5游戏，它将字符数据编码为JSON，然后使用POST将其发送到php文件。 这就是formdata的样子

{"onScreen":3,"quoteNum":4,"CHARACTER1":{"screenPos":1,"charNum":0,"bodyNum":0,"hairNum":0,"eyeNum":0,"hairColNum":0,"name":""},"CHARACTER2":{"screenPos":2,"charNum":0,"bodyNum":0,"hairNum":0,"eyeNum":0,"hairColNum":0,"name":""},"CHARACTER3":{"screenPos":3,"charNum":0,"bodyNum":0,"hairNum":0,"eyeNum":0,"hairColNum":0,"name":""}}:

唯一的问题是我不知道如何在php中检索编码的JSON。 当我只是尝试打印数据时，php只打印“数组”。

我如何简单地让php打印它发布的JSON数据？

Answer 1

在将数据解码为数组之后，尝试在服务器端获取编码的json。

print '<pre>';
print_r(json_decode($_POST,1)) 
print '</pre>'

对于您的信息：您的json字符串末尾包含一个冒号：P
