Question

I want use php curl with oauth to get the JSON data from twitter. Here is my code. return na error message "error":"Timestamp out of bounds".

I want to know, how to make a correct twitter api curl with oauth?

1. what is oauth_consumer_key, oauth_token, oauth_nonce, oauth_signature? am I right?

2. how to solve "error":"Timestamp out of bounds"?

3. how about my curl_setopt method?

In many way, I would like to use this php curl to decode other twitter api(changed url). Thanks a lot.

$callback="<callback url>";
$consumer_key="<Consumer key>";
$consumer_secret="<Consumer secret>";
$oauth_token="<Access Token (oauth_token)>";
$oauth_signature="<Access Token Secret (oauth_token_secret)>";//these key word in my api panel
$time = mktime(date("Y-m-d H:i:s"))-86400;
$url = "https://api.twitter.com/1/friends/ids.json?";
$url .= "user_id=<user id>";
$url .= "&realm=".urlencode($callback)."";
$url .= "&service_provider_id=11";
$url .= "&oauth_consumer_key=".$consumer_key."";
$url .= "&oauth_token=".$oauth_token."";
$url .= "&oauth_nonce=".$consumer_secret."";
$url .= "&oauth_signature_method=HMAC-SHA1";
$url .= "&oauth_timestamp=".$time."";
$url .= "&oauth_version=1.0";
$url .= "&oauth_signature=".$oauth_signature."";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: api.twitter.com'));
$json = curl_exec($ch);
curl_close ($ch);
$data = json_decode($json, true);
print_r($json);

You’re using mktime incorrectly, it doesn’t accept a date string. Instead of that however, I’d recommend that you do …

$time = time() - 86400;

With regards to your other questions, I recommend getting an oauth capable twitter library for PHP. There are plenty out there, and there’s no point in reinventing the wheel … usually 🙂
