将curl响应保存到数据库中

I am getting this response

[{"id":15702671,"payment_id":15702666,"amount":20,"metadata":{},"source":{"id":"347862165","name":"Test Test","type":"collector"},"date_created":"2018-08-28T08:11:15.000-04:00","unique_sequence_number":null,"status":"approved"}]

This is my Code

$url = "https://api.mercadopago.com/v1/payments/".$paymeny_id."/refunds?access_token=TEST-4015220099523401-082300-232be80199d9b1a9b0bac72d6af99fd2-347862165";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
$output = curl_exec($ch);
curl_close($ch);

how to save response value in variable ?

try this

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$var = curl_exec($ch)

Hope this works!

to get the id

$var = json_decode($var);
$id = $var[0]->id;

you need to add CURLOPT_RETURNTRANSFER option in your curl object to get the response using curl as

$url = "https://api.mercadopago.com/v1/payments/".$paymeny_id."/refunds?access_token=TEST-4015220099523401-082300-232be80199d9b1a9b0bac72d6af99fd2-347862165";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);
