如果你的函数返回false或为空，你可以这样做：

if($characters = $_handlerGameServer->fetch($_queryGame['characters'],array($session->get("account")))) {

    foreach ($characters as $character) {
        $buttons .= "<button class='buttonProcess' name='select_character' title='character_id' value='".$character[0]."'>".$character[1]."</button>\n";
    }

    $_templatePage->replace("buttons",$buttons);
} else {
    $_templatePage->replace("buttons",$_lang['error']['noCharacters']."<br /><a href='?page=select_server' class='linkProcess' name='unset_server'>".$_lang['character']['changeServer']."</a> | <a href='?page=account' class='linkProcess' name='logout'>".$_lang['character']['logout']."</a> ");
}
