This article will explain in detail what is the difference between $GLOBALS ['HTTP_RAW_POST_DATA'] and $_ POST in PHP. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

The details are as follows:

$_ POST: an array of variables passed through the HTTP POST method. Is an automatic global variable.

$GLOBALS ['HTTP_RAW_POST_DATA']: always generate a $HTTP_RAW_POST_DATA variable that contains the original POST data. This variable is generated only when data of unrecognized MIME type is encountered. $HTTP_RAW_POST_DATA is not available for enctype= "multipart/form-data" form data.

That means basically $GLOBALS ['HTTP_RAW_POST_DATA'] and $_ POST are the same.

But if the data from post is not recognized by PHP, you can use $GLOBALS ['HTTP_RAW_POST_DATA'] to receive it, such as text/xml or soap, etc.

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

This is what the manual says:

Always generate variables that contain raw POST data. Otherwise, this variable is generated only when data of unrecognized MIME type is encountered. However, a better way to access 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 is useful in cases where the post Content-Type is not something PHP understands (such as text/xml).

That is, basically $GLOBALS ['HTTP_RAW_POST_DATA'] is the same as $_ POST. But if the data from post is not recognized by PHP, you can use $GLOBALS ['HTTP_RAW_POST_DATA'] to receive it, such as text/xml or soap, etc.

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

Use the Content-Type=text/xml type to submit the contents of an xml document to php server, and how to get the 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).

Because PHP only recognizes application/x-www.form-urlencoded standard data types by default, the contents of matching types such as text/xml cannot be parsed into an array of $_ POST, so the prototype is retained and handed over to $GLOBALS ['HTTP_RAW_POST_DATA'] to receive.

There is also a php://input that can also implement this function.

Php://input allows you to read the raw data of POST. It puts less pressure on memory than $HTTP_RAW_POST_DATA and does not require any special php.ini settings. Php://input cannot be used for enctype= "multipart/form-data".
