There is a known bug in php version 522 that does not populate the global variable HTTP_RAW_POST_DATA.

Not strictly an ezP error per se, but nice to have fixed nonetheless

file: \lib\ezsoap\classes\ezsoapserver.php

FIX:
function eZSOAPServer()

{ global $HTTP_RAW_POST_DATA; $this->RawPostData = $HTTP_RAW_POST_DATA; }

becomes:
function eZSOAPServer()
{
$ver = phpversion();
if ($ver[0] >= 5)

{ $this->RawPostData = file_get_contents('php://input'); }

else

{ $this->RawPostData = isset($GLOBALS['HTTP_RAW_POST_DATA']) ? $GLOBALS['HTTP_RAW_POST_DATA'] : ''; }

}

Steps to reproduce

try to access any soap service defined on eZP
