php foreach loop don’t work when I want to traverse json file

My foreach loop dont work. It brings me only 1st item info when i use $arr in my foreach loop but when i change that to $value it gives me nothing 🙁

<?php
      $url = file_get_contents("libs/json/countryBorders.geo.json");
      $arr = json_decode($url,true);
    
    
      foreach($arr as $value)  {
             echo $value['features'][0]['properties']['name'];
             echo $value['features'][0]['properties']['iso_a2'];
       };
        
?>

Here is one of my elements in json file. I want to print all names and iso_a2 codes

{
   "type":"FeatureCollection",
   "features":[
      {
         "type":"Feature",
         "properties":{
            "name":"Bahamas",
            "iso_a2":"BS",
            "iso_a3":"BHS",
            "iso_n3":"044"
         },
         "geometry":{
            "type":"MultiPolygon",
            "coordinates":[

Answer

I didn’t read, that it is a list of your example object. So better follow the other answer :S

You have an JSON Object (it is not an array/list) and I wonder if that even works. You want to get the features of the path “/Features/” right? So you have to change it like the following:

<?php
      $url = file_get_contents("libs/json/countryBorders.geo.json");
      $arr = json_decode($url,true);
    
    
      foreach($arr['features'] as $feature)  {
             echo $feature['properties']['name'];
             echo $feature['properties']['iso_a2'];
      };
?>
