Try this:

$date = DateTime::createFromFormat('h:i A', '08:08 AM');
echo $date->format('H:i:s');   // 08:08:00

$date = DateTime::createFromFormat('h:i A', '08:08 PM');
echo $date->format('H:i:s');  // 20:08:00

If it is 08:08 AM instead of 08:08:AM, this will work for you:

echo date("H:i:s",strtotime("08:08 AM")); //08:08:00
echo date("H:i:s",strtotime("08:08 PM")); //20:08:00

But if it is 08:08:AM, you need to remove that : before AM first and then apply the time:

$time_original = "08:08:AM";
$time = preg_replace("/(\d+):(\d+):(AM|PM)/", "$1:$2 $3", $time_original);
echo date("H:i:s",strtotime($time)); //08:08:00
