这个用PHP怎么读
"results": [
      {
         "currentCity": "广州",
         "pm25": "107",
         "index": [
            {
                  "title": "穿衣",
                  "zs": "炎热",
                  "tipt": "穿衣指数",
                  "des": "天气炎热，建议着短衫、短裙、短裤、薄型T恤衫等清凉夏季服装。"
            },

把Json解析下就好了。

格式化json数组，取出数组results[*].currentCity
