NOW... i want to display this in Unordered list. I have the following function.
public function display($sorted_array)
{
$markup = '';
foreach ($sorted_array as $key => $value)
{
if($key === 'Electronics' || $key ==='Hotels' || $key === 'Services' || $key === 'Entertainment')
{
$markup .= '<h1><li>';
}
$markup .= (is_array($value)) ? '<b>'.$key.'</b></li></ul></h1>'.$this->display($value) : '<ul><li>'.$value. '</li></ul>';
}
return '<ul>'.$markup . '</ul>';
}
