How to get request content (body) in PHP?

Question

I am sending a request to a php server with a XML in the content:

POST /index3.php HTTP/1.0
Connection: Close
Accept: application/xml
Content-Type: text/xml

<?xml version="1.0" encoding="UTF-8"?>
<root />

I've checked in globals vars (like $_GET, $_POST, $_ENV, $_FILES, $_REQUEST...) but they are all empty.

How could I retrieve the content in the server?

Answer 1

Try this

$xml = file_get_contents('php://input');

From the manual:

php://input is a read-only stream that allows you to read raw data from the request body.

Answer 2

Use file_get_contents("php://input") (manual).

In PHP older than 7.0 you could also use $HTTP_RAW_POST_DATA (depending on always_populate_raw_post_data setting).
