      php：代码：

if($act ==\'get_caigou_num\')
{
    $json = new JSON;
    $result = array(\'error\' => \'\', \'content\' => \'\');

    if($_SESSION[\'user_id\'])

        $user_info = $db->getRow("select * from ".$ecs->table(\'users\')." where user_id=\'$user_id\'");
        $user_info[\'username\'] = $user_info[\'user_name\'];
        $smarty->assign(\'user_info\',$user_info);
