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:\Inetpub\Sites\ACR\test.php:12 Stack trace: #0 C:\Inetpub\Sites\ACR\test.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.

 

yeah $_POST is an array so to access the variabl you should put the name of the variable ... so something like this :

$_POST["NAME OF THE VARIABLE SENT"];

 

I have no control over what is sent because it comes from a third party.

The issue is with xml there is no variable name like there is in a form.

Compare it to sending a post with curl

curl_setopt($ch, CURLOPT_POSTFIELDS, $xmlstr);

If I try to read this post using a standard like

foreach( $errors as $_POST => $value ){
if( !isset(${$key}) ){ // Don't clobber existing values
${$key} = $value;
}
if ($debug == 1) {
echo "<P>$key => $value<P>\n"; //testing
}
}

I would get an error message

Warning: Invalid argument supplied for foreach()

 

$postText = trim(file_get_contents('php://input'));
