curl的输出为null

Question

Hello i have never worked with curls in php before, i am trying to get the curl output that i also get when using it in the command line.

Here is what i have tried

$url = 'curl -X "GET" "https://api.spotify.com/v1/me/top/artists" -H "Accept: application/json" -H "Content-Type: application/json" -H "Authorization: MY KEY HERE"';

$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,$url);
$result=curl_exec($ch);
curl_close($ch);

var_dump(json_decode($result, true));

$result = file_get_contents($url);

var_dump(json_decode($result, true));

Those two var_dumps both get me the output NULL.

I am aware that my url is not correct, but i am not sure waht to change.
