unserialize query results not working

[eluser]exodus7[/eluser]
I seem to be having some trouble using unserialize in my view. When I use the following code, im getting a blank list generated with no data :ahhh:

If I change unserialize to a simple echo statement, it displays the serialized data fine. Anyone have an idea?


Controller:

Code:

$this->surveymodel->q15($_POST);
$data['q15'] = $this->surveymodel->q15('survey_results');    
$this->load->view('survey/results', $data);

Model:

Code:

function q15()
{
$q15 = $this->db->query('SELECT q15 FROM survey_results');
return $q15->result();
}

View:

Code:

<ol>
&lt;?
foreach ($q15 as $row)
{
echo "<li>";
   unserialize ($row->q15);
echo "</li>";  
}
?&gt;  
              
</ol>

Thank you
