I'm using The Echo Nest API to find similar artists. The response looks like:
{"response": {"status": {"version": "4.2", "code": 0, "message": "Success"}, "artists": [{"name": "Audio Adrenaline", "id": "ARGEZ5E1187FB56F38"}, {"name": "Tree63", "id": "ARWKO2O1187B9B5FA7"}]}}
How can I take the artists it results and put them into an array? So I can then echo them later like:
echo $artist[0];
You just need to use json_decode() with the second parameter set to TRUE.
$str = '...';
$json = json_decode($str, TRUE);
$artist = $json['response']['artists'];
//$artist = json_decode($str, TRUE)['response']['artists']; as of PHP 5.4
print_r($artist);
Output:
Array
(
[0] => Array
(
[name] => Audio Adrenaline
[id] => ARGEZ5E1187FB56F38
)
[1] => Array
(
[name] => Tree63
[id] => ARWKO2O1187B9B5FA7
)
)
json_decode() is what you need
$artist = json_decode($json);
or as an associative array
$artist = json_decode($json, true);
Use json_decode, found here.
Sample:
$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
var_dump(json_decode($json));
Output:
object(stdClass)#1 (5) {
["a"] => int(1)
["b"] => int(2)
["c"] => int(3)
["d"] => int(4)
["e"] => int(5)
}
