Getting next in array

[iversonm]

public function Get_Photo_Key($UID, $PID, $AID){
$Photos=$this->Get_Photos($UID, $AID);
$Current=reset($Photos);
foreach($Photos as $Value){
     if($Value[0]==$PID){
return array('Next'=>next($Current), 'Previous'=>prev($Current));
}
$Current=next($Photos);
}
}

And just so you know what the Get_Photos function is

public function Get_Photos($UID, $AID){
	global $Database;
	$Result=$Database->Get_Photos($UID, $AID);
	while ($Array[] = mysql_fetch_row ($Result));
	return $Array;
}

$aid=album id

$pid=picture id

$uid=user id

 

i want it to return the next id in order when calling the first function any ideas?
