About receiving a POST request $GLOBALS [' Http_raw_post_data ']

Always produce a variable containing the original POST data. Otherwise, this variable is only generated when it encounters data that does not recognize the MIME type. However, a better way to access the raw POST data is php://input. $HTTP _raw_post_data is not available for enctype= ' multipart/form-data ' form data.

Question: $HTTP _raw_post_data = = $_post?

According to the manual, the answer should be no.
If not, what is the difference between them?


I know the answer, as follows:

The raw/uninterpreted HTTP POst information can be accessed with:
$GLOBALS [' Http_raw_post_data ']
This was useful in cases where the post content-type are not something PHP understands (such as Text/xml).

Other wordsbasically $globals[' http_raw_post_data '] and $_post are the same. But if the POST data is not recognized by PHP, you can use $GLOBALS [' Http_raw_post_data '] to receive it, such as text/xml or soap, and so on.

PHP default recognized data type is the application/x-www.form-urlencoded standard data type

With the Content-type=text/xml type, submit an XML document content to the PHP server, how to get this post data.

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).

Since PHP only recognizes the application/x-www.form-urlencoded standard data type by default, the contents of the type such as text/xml cannot be parsed into the $_post array, so the prototype is retained and given to $globals[' Http_raw_ Post_data '] to receive.

There is also a php://input that can be implemented with this function

Php://input allows the raw data to be read from the POST. Compared to $HTTP _raw_post_data, it brings less pressure to memory and does not require any special php.ini settings. Php://input cannot be used for enctype= "Multipart/form-data".

This method is often used in the XML data that is submitted by the transfer.
