TP5 模板渲染问题

1.如果array是一个对象，就没必要循环。而且它是一条不是多条

如：

配电室名称：{$unusual_detail_info.switching_room.room_name}
配电室厂站：{$unusual_detail_info.switching_room.room_station}
比如这些就只需要加上键名即可

["warning_id"] => int(11)获取这个只需要获取这个键名即可

["warning_time"] => int(1539762874)

array(4) {
  ["warning_id"] => int(11)
  ["warning_time"] => int(1539762874)
  ["warning_description"] => string(15) "转换机短路"
  ["switching_room"] => array(16) {
    ["switching_room_id"] => int(112)
    ["room_name"] => string(26) "软件园26之七配电室"
    ["room_building"] => int(17)
    ["watch_name"] => string(12) "值班人员"
    ["manager_name"] => string(12) "监管人员"
    ["room_station"] => string(15) "思明区总站"
    ["spot_name"] => string(15) "软件园二期"
    ["room_description"] => string(15) "2段进线PT柜"
    ["machine_code"] => string(10) "px20181025"
    ["province_id"] => int(4)
    ["city_id"] => int(60)
    ["district_id"] => int(587)
    ["room_pic"] => array(7) {
      ["file_id"] => int(34)
      ["is_image"] => bool(false)
      ["image_width"] => int(1440)
      ["image_height"] => int(900)
      ["sync"] => bool(true)
      ["url"] => string(53) "/upload/20180824/c4c1b13e72aaf673729269957146b07e.jpg"
      ["full_url"] => string(67) "http://new.com/upload/20180824/c4c1b13e72aaf673729269957146b07e.jpg"
    }
    ["city"] => string(6) "厦门"
    ["manager"] => string(12) "监管人员"
    ["worker"] => string(12) "监管人员"
  }
}
