Description:
------------
tryning to get the object type that i was specified in classmap option. i ever get a object of the type stdClass.

I'm expecting to get in this case a instance of the Class PHPObject previusly declared by me.

I already search for related bug reports and just has found this:
http://bugs.php.net/bug.php?id=42157
thats already closed.

Reproduce code:
---------------
SERVER(teste_ser.php):
<?php

ini_set("soap.wsdl_cache_enabled", "0"); 

class PHPObject
{
	public $prop1;
	public $prop2;
	public $propc;

	public function __construct($a, $b, $c)
	{
		$this->prop1 = $a;
		$this->prop2 = $b;
		$this->propc = $c;
	}
}

function send($arg_obj)
{
	$obj = new PHPObject("SERVER_1", "SERVER_2", "SERVER_3");
	return $obj;
}

$classmap = array('WSDLObject' => 'PHPObject');

$server = new SoapServer("teste.wsdl", array('classmap' => $classmap));

$server->addFunction(array("send"));

$server->handle();

?>
=============================================
CLIENT(teste_cli.php):
<?php

ini_set("soap.wsdl_cache_enabled", "0"); 

class PHPObject
{
	public $prop1;
	public $prop2;
	public $propc;

	public function __construct($a, $b, $c)
	{
		$this->prop1 = $a;
		$this->prop2 = $b;
		$this->propc = $c;
	}
}

try {
	
	$classmap = array('WSDLObject' => 'PHPObject');
	
	$client = new SoapClient("teste.wsdl", array("classmap"  => $classmap, 'trace' => 1));

	$arg_obj = new PHPObject("ARG_1", "ARG_2", "ARG_3");
    
	$res = $client->send($arg_obj);
	
	echo "<hr>RESPONSE FROM SERVER<hr><pre>";
	var_dump($res);
	echo "</pre><hr>";

	echo "<hr>SOAP RESPONSE<hr><pre>";
	echo htmlspecialchars(str_replace("><", ">\n<", $client->__getLastResponse()));
	echo "</pre><hr>";
	
} catch (SoapFault $sf) {
	
	echo "<hr><pre>";
	print_r("(" . $sf->faultcode . ") " . $sf->faultstring);
	echo "</pre><hr>";
	
} catch (Exception  $e) { 
	
	echo "<hr><pre>";
	print_r($e);
	echo "</pre><hr>";

Your have three errors in your report.

1) In WSDL file you've forgot <schema> tag inside <types> element:

<xsd:schema targetNamespace="http://schemas.nothing.com">
  <xsd:complexType  name="WSDLObject">
    <xsd:sequence>
      <xsd:element minOccurs="1" name="param1" type="xsd:string"/>
      <xsd:element minOccurs="1" name="param2" type="xsd:string"/>
      <xsd:element minOccurs="1" name="param3" type="xsd:string"/>
    </xsd:sequence>
  </xsd:complexType>
</xsd:schema>

2) You shuold use "rpc/encoded" instead of "document/literal" encoding, or the envilope won't contain type name and it cannot be used to restore object of proper class.

3) PHPObject ius incompatible with WSDL type. The first one has $prop1 but the second one $param1.
