Netsuite API throws 400 bad request - php

Question

I am trying to connect with Netsuite Customer API but it throws "400 bad request"
Here is my code in PHP
<?php
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "https://xxxxxxx-sb1.suitetalk.api.netsuite.com/services/rest/record/v1/customer/1",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_FAILONERROR => true,
CURLOPT_SSL_VERIFYHOST=>false,
CURLOPT_SSL_VERIFYPEER=>false,
CURLOPT_HTTPHEADER => array(
"Authorization: OAuth realm=\"xxxxxxx_SB1\",oauth_consumer_key=\"consumer_key_xxxxxx\",oauth_token=\"auth_token_xxxxxxxx\",oauth_version=\"1.0\""
),
));
$response = curl_exec($curl);
if (curl_errno($curl)) {
$error_msg = curl_error($curl);
}
var_dump($error_msg);
curl_close($curl);
var_dump($response);
?>
Here above code I copied from postman. In a postman, it returns data but when I copied code for php in a file it is not working, Could anyone suggest me where I am going to wrong ?
My localhost url : localhost/netsuite_api.php

For whatever reason, the netsuite API returns 400 even where it should be a 401 according to the docs.
From the docs about the Authentication, you need to send more fields (see page 169 following):
Authorization:
OAuth realm="12345",
oauth_consumer_key="4a3ff6c251a55057bb1e62d8dc8998a0366e88f3a8fe735265fc425368b0f154",
oauth_token="52cfe88fecf2e2b74e833e7dfc4cae79ff44c3ca9f696d61e2a7eac6c8357c3c",
oauth_nonce="qUwlmPvtGCS4sHJe8F7x",
oauth_timestamp="1462453273",
oauth_signature_method="HMAC-SHA1", oauth_version="1.0",
