这是首次打开新店在页面上方出现的，刷新后就没有了。
下边是这个文件的源码：

回答：
源程序的小问题，修改 _get_app()方法
function _get_apps() {
$this->base->load('app');
$apps = $_ENV['app']->get_apps();
$apps2 = array();
if(is_array($apps)) {
foreach($apps as $v) {
if(!is_array($v['extra'])){
$v['extra'] = unserialize($v['extra']);
}
$apps2[$v['appid']] = $v;
}
}
return $apps2;
}
