The RAW / uninterpreted HTTP POst information can be accessed with:? ?$GLOBALS[\'HTTP_RAW_POST_DATA\']This is useful in cases where the post Content-Type is not something PHP understands (such as text/xml).也就是说,基本上$GLOBALS[\'HTTP_RAW_POST_DATA\'] 和 $_POST是一样的。但是如果post过来的数据不是PHP能够识别的,你可以用 $GLOBALS[\'HTTP_RAW_POST_DATA\']来接收,比如 text/xml 或者 soap 等等。
