Question

I got this big problem,and I can’t find a solution..
I got this Json being returned to me from an API,but I don’t really know how can I get the name of the hero by using his id ?

[
{ "id":0, "name":"N/A"  },
{ "id":1, "name":"John" },
{ "id":2, "name":"Doom" }
]

Tried something like :

$data = json_decode($json,true); 
$id = $data[0]['id'];
$name = $data[0][$id]['name'];

But I can’t really make this work…
Thank you in advance!

Answer 1

in your example you are looking to get index ‘0’ in the JSON array, index 0 would be:

{ "id":0, "name":"N/A"  }

This index 0 is now a key-value pair so you can simply call

$id = $data[0]['id'];
$name = $data[0]['name'];

If you wanted to do it for all of the elements in the array then you could use a for-loop or a foreach-loop.

To get the name for the ID you would have to do something like the following:

function name_for_id($data, $id) {

  foreach ($data as $value) {

    if ($value['id'] == $id)
      return $value['name'];

  }
}
