function get_team_list() {

/* 获取团队列表 */
$sql = "SELECT * FROM " . $GLOBALS['dou']->table('team') . " ORDER BY sort ASC, id ASC";


$query = $GLOBALS['dou']->query($sql);
while ($row = $GLOBALS['dou']->fetch_array($query)) {

$team_list[] = array (
"id" => $row['id'],
"name" => $row['name'],
"team_style" => $row['team_style'],
"class" => $row['class'],
