How to use curl to get streaming data from twitter in php - php

Question

I trying to get streaming data from twitter, I found curl in twitter developer section to get streaming data
$ curl --request GET
--url 'https://api.twitter.com/1.1/search/tweets.json?q=nasa&result_type=popular'
--header 'authorization: OAuth oauth_consumer_key="consumer-key-for-app",
oauth_nonce="generated-nonce", oauth_signature="generated-signature",
oauth_signature_method="HMAC-SHA1", oauth_timestamp="generated-timestamp",
oauth_token="access-token-for-authed-user", oauth_version="1.0"'
But i found how to use curl to get data at http://collaboradev.com/2011/04/01/twitter-oauth-php-tutorial/ But I am getting
{"errors":[{"code":215,"message":"Bad Authentication data."}]}
I checked my credential but could not solve ,problem persists: My code is below ::
$nonce = time();
$timestamp = time();
$oauth = array('oauth_callback' => 'https://localhost/twitter/curl.php',
'oauth_consumer_key' => 'bGLk7nhcMySEulFeRICCMdmtk',
'oauth_nonce' => $nonce,
'oauth_signature_method' => 'HMAC-SHA1',
'oauth_timestamp' => $timestamp,
'oauth_version' => '1.0');
function buildAuthorizationHeader($oauth){
$r = 'Authorization: OAuth '; //header prefix
$values = array(); //temporary key=value array
foreach($oauth as $key=>$value)
$values[] = "$key=\"" . rawurlencode($value) . "\""; //encode key=value string
$r .= implode(', ', $values); //reassemble
return $r; //return full authorization header
}
$header = array( buildAuthorizationHeader($oauth), 'Expect:');
$options = array(CURLOPT_HTTPHEADER => $header, //use our authorization and expect header
CURLOPT_HEADER => false, //don't retrieve the header back from Twitter
CURLOPT_URL => 'https://api.twitter.com/1.1/search/tweets.json?q=nasa&result_type=popular', //the URI we're sending the request to
CURLOPT_POST => true, //this is going to be a POST - required
CURLOPT_RETURNTRANSFER => true, //return content as a string, don't echo out directly
CURLOPT_SSL_VERIFYPEER => false);
$ch = curl_init(); //get a channel
curl_setopt_array($ch, $options); //set options
$response = curl_exec($ch); //make the call
curl_close($ch); //hang up
echo $response;
