$leibie_new[] = $value['xminfo'];
开始
结束
1、形成的数据结构赋值$front_arr['salve_data']，2、$front_arr['xminfo'] = $leibie_new
组织数据结构$salvedata_new2[$key]['id'] = $value['khx_id'];$salvedata_new2[$key]['xmid'] =$value['id'];
形成新的数据集合用符号$salvedata_new表示
循环$salvedata_new as $key = $value
外循环$front_arr['leibie'] as $key = $value
内循环$value['salve_data'] as $key = $value2
$front_arr['leibie']
