Issue reading HTTP request body from a JSON POST in PHP

I'm writing a script that is registered as an endpoint for a webhook. I know that it's successfully registered because I'm writing the header of every request to my server logs. Here's a sample:

Content-Type: text/xml; charset=UTF-8
User-Agent: Jakarta Commons-HttpClient/3.1
Host: =={obfuscated}==
Content-Length: 1918


The API that I've registered with is POST-ing a JSON object to my script, and I'd like to parse that object using PHP. As you can see from the request header, there's a nice big fat JSON object waiting to be parsed. It seems straightforward, but it hasn't been.

At first I tried using
$_POST['json']
or just
$_POST
but since the data isn't in an array, I wasn't really sure how to access it like that.

I've tried using
file_get_contents('php://input')
and
fopen('php://input', 'r')
with and without
json_decode()
but no luck. I can't use
http_get_request_body()
since the server I'm on doesn't have PECL and that's out of my control.

Are there any other ways to interact with the POST-ed JSON object that I'm missing? Thanks!

Answer

Thanks to others for the input. It turns out that I just needed

$inputJSON = file_get_contents('php://input');
$input = json_decode($inputJSON, TRUE); //convert JSON into array

where the second parameter in json_decode returned the object as an array.

Hope this helps someone else!
