php處理json請求（php獲取post請求的json數據的實現方法）

PHP默認只識別application/x-www.form-urlencoded標準的數據類型，所以，對型如text/xml 或者 soap 或者 application/octet-stream 之類的內容沒法解析，若是用$_POST數組來接收就會失敗！故保留原型，交給$GLOBALS['HTTP_RAW_POST_DATA'] 來接收

---------------------------------------------------

參考：

Fiddler進行模擬Post提交json數據，總爲null解決方式

Request Headers:

User-Agent: Fiddler
Host: localhost:3248
Content-Type: application/json; charset=utf-8  
Content-Length: 63

要加上Content-Type: application/json; charset=utf-8，要不是JSON沒效

Request Body

{"UserID":4,"UserName":"Parry","UserEmail":"Parry@cnblogs.com"}

緊記，不要寫成這樣：[{"UserID":4,"UserName":"Parry","UserEmail":"Parry@cnblogs.com"}]
