[PHP] Overloaded Class The __tostring() Method

2004-08-20 Thread Daniel Schierbeck 
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:
errorObject id #1/error
Can someone help me? I want to print the contents of the $error object 
as well...

Not sure if that's exactly what you're after, though...

It's more the principle of automatically building the string... I just 
used the error thing as an example. What i'd like to do is to be able to 
create an XML string out of an object, no matter how many levels of 
properties that object has.
