Subject: [PHP] Overloaded Class & The __tostring() Method


I am trying to build an XML-formatted string from an object. I use this 
code:

<?php
class XML_Object
{
private $childs = array();
public function __get ($prop)
{
if (isset($this->childs[$prop])) {
return $this->childs[$prop];
} else {
trigger_error("Property '$prop' not defined.", E_USER_WARNING);
}
}
public function __set ($prop, $val)
{
$this->childs[$prop] = $val;
}
public function __tostring ()
{
$re = "";
foreach ($this->childs as $key => $val) {
$re .= "<$key>$val</$key>";
}
return $re;
}
}
$error = new XML_Object;
$error->no = 2;
$error->str = "Blablabla";
$error->file = "a_file.php";
$error->line = 54;
$xml = new XML_Object;
$xml->error = $error;
echo $xml;
?>
But i only get this response:
<error>Object id #1</error>
Can someone help me? I want to print the contents of the $error object 
as well...
echo $xml->error->no;
echo $xml->error->str;
etc...
Not sure if that's exactly what you're after, though...
