How Do i translate command line curl commang into PHP curl call?

Question

Here is the command line command:

curl -H "Authorization: Bearer API_KEY" -X PUT https://graph.api.smartthings.com/api/smartapps/installations/DEVICE_ID/lock

Here is what i have uptill now, what is wrong with this code:

$headers = array('Authorization: Bearer ' . $st_api_token);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
$response = curl_exec($ch);
curl_close($ch);

Output for var_dump(curl_getinfo($ch)); is, I am still unable to find the real error or i am doing something wrong in translating this code to PHP:

    <?php array (size=26)

After searching on internet i got this issue fixed by changing headers array and adding curl settings:

$headers = array('Authorization: Bearer ' . $st_api_token,
    'Content-Type: application/json',
    'Accept: json',
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST , false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$response = curl_exec($ch);
curl_close($ch);
