小编Mic*_* C.的帖子

我从Instagram上拉JSON:

$instagrams = json_decode($response)->data;

然后将变量解析为PHP数组以重构数据,然后重新编码和缓存文件:

file_put_contents($cache,json_encode($results));

当我打开缓存文件时,所有正斜杠"/"都被转义:

http:\/\/distilleryimage4.instagram.com\/410e7...

我从搜索中收集json_encode()自动执行此操作...有没有办法禁用它？

寻找一个简单的JS来计算.json文件中的项目数(每个项目代表,在这种情况下,一张Instagram照片被拉入网络应用程序;我想计算照片的数量).因此,Json的结构......

{
 "type":"FeatureCollection",
 "features":[
  {
     "type":"Feature",
     "geometry":{
        "coordinates":[
           -79.40916,

        "type":"Point"
     },

     }
  },

我只想循环遍历json文件并计算项目数.完全迷失在哪里开始.
