function echoTwoStrings($inputString1, $inputString2)
{
    return array("outputString1" => $inputString1,
                 "outputString2" => $inputString2);
}
$server->addFunction(array("echoString", "echoTwoStrings"));

Be careful with SOAP_FUNCTIONS_ALL, as it adds ALL availiable PHP functions to your server.

This can be a potential security threat, imagine clients doing this:

echo $client->file_get_contents("c:\\my files\\my_passwords.doc");

And voila, they have the contents of your file my_passwords.doc.

In response to comment by Nathan O'Sullivan about returning (or passing) a complex type, you can also use the stdClass() object.

Assume you define a complex type like so:

<xsd:complexType name="TestType">
        <xsd:all>
                <xsd:element name="A" type="xsd:string" />
                <xsd:element name="B" type="xsd:int" />
                <xsd:element name="C" type="xsd:boolean" />
        </xsd:all>
</xsd:complexType>

To use an object in place of an array you can do:

$test = new stdClass();
$test->A = "test string";
$test->B = 45;
$test->C = false;

$result = $client->Test($test);

function Login($username, $password)
{
  return array("LoginResult" => array("Id"=>1, "Name"=>"Nathan", "Nickname"=>"Nathan", "Email"=>"email address") );
}

Ok, Only a litte error in the last note.. :
"LoginResult" => array    and NOT      "LoginResult" , array

You may be left wondering, as I was, how to return a complex type - consider the following WSDL snippets, for a method called Login:

 <xs:element name="Login">
        <xs:complexType>
          <xs:sequence>
            <xs:element minOccurs="0" maxOccurs="1" name="username" type="xs:string" />
            <xs:element minOccurs="0" maxOccurs="1" name="password" type="xs:string" />
          </xs:sequence>
        </xs:complexType>
      </xs:element>

   <xs:complexType name="UserInfo">
        <xs:sequence>
          <xs:element minOccurs="0" maxOccurs="1" name="Id" type="xs:string" />
          <xs:element minOccurs="0" maxOccurs="1" name="Name" type="xs:string" />
          <xs:element minOccurs="0" maxOccurs="1" name="Nickname" type="xs:string" />
          <xs:element minOccurs="0" maxOccurs="1" name="Email" type="xs:string" />
        </xs:sequence>
      </xs:complexType>

   <xs:element name="LoginResponse">
        <xs:complexType>
          <xs:sequence>
            <xs:element minOccurs="0" maxOccurs="1" name="LoginResult" type="s0:UserInfo" />
          </xs:sequence>
        </xs:complexType>
      </xs:element>

Here's a working Login function  that I've added with add SoapServer::addFunction

function Login($username, $password)
{
  return array("LoginResult", array("Id"=>1, "Name"=>"Nathan", "Nickname"=>"Nathan", "Email"=>"email address") );
}

The UserInfo complextype is represented by the inner array.  The outer array has just one element, "LoginResult".  The LogineResponse element  seems to be treated as a one-member array by PHP.
