Description:
------------
Hi,

When I use the SetClass method in my SoapServer object, it only triggers a constructor with the name of the class: ClassName() and not __construct. It happens when I don't even have a constructor called ClassName(), so it's not a problem of the order in which the Zend Engine looks for constructors. It simply always ignores __construct().

Reproduce code:
---------------
class SoapHandler
{
  function __construct($param)
  {
    die($param);
  }
}

$soap = new SoapServer(NULL, array("uri" => "urn:myurn"));
$soap->setClass("SoapHandler", "myparam");


Expected result:
----------------
output:

myparam

Actual result:
--------------
no output

rename the __construct to SoapHandler() and it will work as expected
