The above feature will cause a slight trouble since the name of the variable will always be "wddxtemp" but you can use preg_replace to fix that.
Also, a better approach is to serialize the entire class. WDDX will that write a reserved "php_class_name" variable which can be used to reconstruct the class during a deserialize.

You can use globals to get around the above in classes:
<?php
class Test
{
var $str;
var $wddx;
function Test()
{
$this->str = "test";
$this->wddx_serialize($this->str);
header('Content-Type: text/xml');
echo ($this->wddx);
}
function wddx_serialize($var) {
global $wddxtemp;
unset($wddxtemp);
$wddxtemp = $var;
$this->wddx = wddx_serialize_vars("wddxtemp");
}
}
new Test();
?>

Be careful using WDDX - functions on object variables. As I just had to find out the following won't work:
<?php
class Test
{
var $str;
var $wddx;
function Test()
{
$this->str = "test";
$this->wddx = wddx_serialize_vars("this->str");
print(htmlentities($this->wddx));
}
}
new Test();
?>
That's what you'll get:
<wddxPacket version='1.0'><header/><data><struct></struct></data></wddxPacket>
