How to read an xml file sent via http post

How to read an xml file sent via http post

I’ve tried a few solutions

$xml = new SimpleXMLElement($_POST);

This gives and error

Fatal error: Uncaught exception ‘Exception’ with message ‘SimpleXMLElement::__construct() expects parameter 1 to be string, array given’ in C:InetpubSitesACRtest.php:12 Stack trace: #0 C:InetpubSitesACRtest.php(12): SimpleXMLElement->__construct(Array) #1 {main} thrown

Fatal error: Call to undefined function simple_xml_loadstring() in

Yet I know the function itself works because I have used it with curl when I have received a string back

$reply = curl_exec($ch);
$xml=simplexml_load_string($reply);

So I assume my problem is my $_POST is a array and not a string. So my question is how to extract my xml from my post variable so I can read it correctly

Also in #PHP _↴
