[PHP-SOAP-DEV] Proposed overriding ser/deser

[brad l. <rod...@ya...>]

I have been doing some thining on how to do this...

And i think it would be pretty cool if i could incorperate domxml.

Standard function handing:
$soap_server->map("namespace:type", "to_xml", "to_zval");

function to_xml_before($zval)
{
 return $modified_zval;
}

function to_xml($zval)
{
  $xmldom_node = new DomElement($zval->name);
  $xmldom_node->set_content($zval->value);
  return $xmldom_node;
}

function to_xml_after($xmldom_node)
{
  $xmldom_node->first_child()->unlink_node();
  return $xmldom_node;
}

-------------

function to_zval_before($xmldom_node)
{
 return $xmldom_node->first_child()->unlink_node();
}

function to_zval($xmldom_node)
{
 $zval->data = $xmldom_node->first_child()->get_content();
 return $zval;
}

function to_zval_after($zval)
{
 $zval->connection = db_connect($zval->db, $zval->username, $zval->passwd);
  - or -
 unset($zval->unwanted_field);
  - or -
 $obj = new OtherObject($zval->value);

 return $obj;
}

Class manipulation.

$soap_server->map("namespace:type", "class", MAP_CLASS_INSTANCE (default) |
MAP_CLASS_CONVERT);

MAP_CLASS_INSTANCE:
class myType
{
 function to_xml_before()
 {
   unset($this->unwanted);
 }

 function to_xml()
 {
  $xmldom_node = new DomElement($this->name);
  $xmldom_node->set_content($this->value);
  return $xmldom_node;
 }

 function to_xml_after($xmldom_node)
 {
  $xmldom_node->first_child()->unlink_node();
  return $xmldom;
 }

 function to_zval_before($dom_node)
 {
  $xmldom_node->first_child()->unlink_node();
  return $xmldom;
 }

 function to_zval($xmldom_node)
 {
  $this->data = $xmldom_node->get_contents();
 }

 function to_zval_after()
 {
  unlink($this->data);
 }
}

MAP_CLASS_CONVERT:
class myType
{
function to_xml_before($zval)
{
 return $modified_zval;
}

function to_xml($zval)
{
  $xmldom_node = new DomElement($zval->name);
  $xmldom_node->set_content($zval->value);
  return $xmldom_node;
}

function to_xml_after($xmldom_node)
{
  $xmldom_node->first_child()->unlink_node();
  return $xmldom_node;
}

function to_zval_before($xmldom_node)
{
 return $xmldom_node->first_child()->unlink_node();
}

function to_zval($xmldom_node)
{
 $zval->data = $xmldom_node->first_child()->get_content();
 return $zval;
}

function to_zval_after($zval)
{
 $zval->connection = db_connect($zval->db, $zval->username, $zval->passwd);
  - or -
 unset($zval->unwanted_field);
  - or -
 $obj = new OtherObject($zval->value);

 return $obj;
}
}

Basically the difference between MAP_CLASS_INSTANCE and MAP_CLASS_CONVERT is
the instance treats the class as the type thats being converted and the
class_convert treats the class as just a "conversion" class.

$soap_server->autoMap(true/false);

This will tell the server to "automap" types. Meaning if
while serializing/deseralizing "someType" and there is an
existing php class called "someType" then it ill try and call
the corrisponding functions.


I was looking into the domxml extension. The extension will need some changes
for my needs and some other issues that dont currently work right now. 
like:

$xml = new DomElement("asdf");

doesn't really give you a new DomElement();
you have to do:

$xml = new DomElement("asfd");
$real_xml = $xml->domelement("asdf");

it looks like the constructors aren't working. I know how to fix them its just
a matter of getting in the changes.

the extension could still handle the
to_xml_before()
and
to_zval_after()
 with out domxml changes or if domxml isn't even compiled in.
