Converting timestamp

[steven s]

This is actually something for PhotoPost Classfieds.
I think I have a better chance here getting a hand here.
I added this to a rss script
enddate is the ending timestamp of the ad

PHP Code:

// expiration date
 if ( !empty($data['enddate']) ) $data['enddate'] = "<br /><br />Expires: ". $data['enddate']; 


and

PHP Code:

$item->description = "$thumb<br /><br />Posted by: ". $data['user'] . $data['description']. $data['enddate']; 


As written it posts the *nix timestamp.
I have used $newenddate = formatppdate($enddate) in another place but don't know how to reformat enddate here.
