                )";
    $sth = $db->prepare($query);
    $sth->execute(array(

        ':lastname' => $lastname,
        ':age' => $age,
        ':birthplace' => $birthplace,

    $id = $db->lastInsertId();
    return $id;

and i'm trying to return the last ID that was inserted, and all i'm getting is a 0 returned. any help is greatly appreciated thanks

LAST_INSERT_ID() and friends will work only for integer IDs that are created via an AUTO_INCREMENT column. You need to run two queries - first

SELECT UUID() AS newuuid;

then fetch and store this result (e.g. in $uuid), then

"INSERT INTO players VALUES (
                    :uuid,
                    :firstname,
                    :lastname,
...
execute(array(
        ':uuid' => $uuid,
        ':firstname' => $firstname,
        ':lastname' => $lastname,
        ':age' => $age,

leaving you with the $uuid still valid.
