运行PHP项目时，一直弹出这个提示

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

解决方法：

php.ini文件下：开启always_populate_raw_post_data = -1 之后保存重启即可

原因：开启后就可以用 $HTTP_RAW_POST_DATA 接收data，不过通常我们使用 php://input
