運行PHP項目時，一直彈出這個提示
Deprecated: Automatically populating $HTTP_RAW_POST_DATA is deprecated and will be removed in a future version. To avoid this warning set 'always_populate_raw_post_data' to '-1' in php.ini and use the php://input stream instead. in Unknown on line 0
Warning: Cannot modify header information - headers already sent in Unknown on line 0
解決方法：
php.ini文件下：開啟always_populate_raw_post_data = -1 之后保存重啟即可
原因：開啟后就可以用 $HTTP_RAW_POST_DATA 接收data，不過通常我們使用 php://input
