Alternative method to display specific JSON data in PHP

I am extracting data from a JSON file using a URL like this:

$html5=file_get_contents("url");

$data = json_decode($html5);    

echo $data->a->k->f;

This displays $27.58 which is correct.

Here is my JSON data:

{  
"a":{  
   "k":{  
     "c":"tr",
     "f":"$27.58",
     "fb":"$30.35",
     "ci":"12873809",
     "cname":"Cdkeysgame_com",
     "ep":"26.05",
     "epb":"28.66",
     "a":"5473091",
     "it":"steam",
     "sl":"0",
     "l":null,
     "lt":null,
     "x":0,
     "v":"retail",
     "ne":0,
     "so":0,
     "tr":304,
     "r":97,
     "cf":1,
     "p":"27.58317275",
     "pb":"30.3467843",
     "eci":"865723abbf1cbb952ad4d2da8a8c925e"
  },
  "k_1":{  
     "c":"gb",
     "f":"$27.64",
     "fb":"$30.40",
     "ci":"1065801",
     "cname":"World_of_games",
     "ep":"26.10",
     "epb":"28.71",
     "a":"781851",
     "it":"steam",
     "sl":"0",
     "l":null,
     "lt":null,
     "x":0,
     "v":"all",
     "ne":0,
     "so":0,
     "tr":1041328,
     "r":99,
     "cf":1,
     "p":"27.6361155",
     "pb":"30.39972705",
     "eci":"d01a7cacb0e424123985bfe2e53a0523"
  },
  "k_2":{  
     "c":"ch",
     "f":"$27.68",
     "fb":"$30.44",
     "ci":"696012",
     "cname":"G_hard",
     "ep":"26.14",
     "epb":"28.75",
     "a":"1287052",
     "it":"steam",
     "sl":"0",
     "l":null,
     "lt":null,
     "x":0,
     "v":"retail",
     "ne":0,
     "so":0,
     "tr":10818,
     "r":99,
     "cf":1,
     "p":"27.6784697",
     "pb":"30.44208125",
     "eci":"a6666c0a47acb70d14b757cd52f1b9cc"
  }}

I need to display the same data without using k. For example I want to:

 echo $data->a->'Something that specifies first element of 'a' i.e k and not'k_1' and 'k_2'->f;

Since I am scraping this content I cannot change anything like structure or data in this JSON file.

If you just want the first entry under a, then you can decode as an array:

$data = json_decode($json, true);

Then get the first element of $data['a'] and use that. current() will also work:

echo reset($data['a'])['f'];

Or re-index $data['a'] numerically and access the first one 0:

echo array_values($data['a'])[0]['f'];

To catch them all:

foreach($data['a'] as $values) {
    echo $values['f'];
    //break; if you only want the first one
}

You can do this so:

$object = json_decode($html5);

foreach ($object->a as $element) {
   echo $element->f;
}
