Comment puis-je récupérer les valeurs...

Comment puis-je récupérer les valeurs recueillies par ce code :

<?
class BEncoderException extends Exception {}

class BEncoder

public $encoded;

private $_offset = 0;

public function decode ($str = null)

private function _decodeInt ()

if ($end === false) throw new BEncoderException ('Decoding error at: ' . $this->_offset);
$result = (double) substr ($this->encoded, $this->_offset + 1, $end - $this->_offset - 1);

break;

ksort ($value);

}

private function _encodeList ($value)
{

foreach ($value as $item)

return $result . 'e';
}

private function _encodeDictionary ($value)
{

return $result . 'e';
}

private function _encodeInt ($value)
{

?

je désire recueillir les valeurs chacune dans une variable exploitable.

Merci de votre aide
