Twitter recently turned off their v1.0 API which broke a multitude of applications, many of which are still broken today. I had the need to immediately update at least one website to the new Twitter v1.1 API, but I could not find a simple bare bones example on the internet. Pretty much all the code/libraries out there I could find for the new API version were hundreds to thousands of lines long, or didn’t work >.<; . So anywho, here is the simple PHP code I put together to make API calls.
This code requires certain consumer/authentication keys and secrets. You can find how to generate them elsewhere online.
//OAuth Request parameters
$ConsumerKey='FILL ME IN';
$ConsumerSecret='FILL ME IN';
$AccessToken='FILL ME IN';
$AccessTokenSecret='FILL ME IN';
function EncodeParam($input) { return strtr(rawurlencode($input), Array('+'=>' ', '%7E'=>'~')); }
function SendTwitterRequest($RequestURL, $Params=Array())
{
//Compile the OAuth parameters
global $ConsumerKey, $ConsumerSecret, $AccessToken, $AccessTokenSecret;
$Params=array_merge(
$Params,
Array('oauth_version'=>'1.0', 'oauth_nonce'=>mt_rand(), 'oauth_timestamp'=>time(), 'oauth_consumer_key'=>$ConsumerKey, 'oauth_signature_method'=>'HMAC-SHA1'),
isset($AccessToken) ? Array('oauth_token'=>$AccessToken) : Array()
);
uksort($Params, 'strcmp'); //Must be sorted to determine the signature
foreach($Params as $Key => &$Val) //Create the url encoded parameter list
$Val=EncodeParam($Key).'='.EncodeParam($Val);
$Params=implode('&', $Params); //Combine the parameter list
$Params.='&oauth_signature='.EncodeParam(base64_encode(hash_hmac('sha1', 'GET&'.EncodeParam($RequestURL).'&'.EncodeParam($Params), EncodeParam($ConsumerSecret).'&'.EncodeParam($AccessTokenSecret), TRUE)));
//Do the OAuth request
$CurlObj=curl_init();
foreach(Array(CURLOPT_URL=>"$RequestURL?$Params", CURLOPT_SSL_VERIFYHOST=>0, CURLOPT_SSL_VERIFYPEER=>0, CURLOPT_RETURNTRANSFER=>1) as $Key => $CurlVal)
curl_setopt($CurlObj, $Key, $CurlVal);
$Result=curl_exec($CurlObj);
curl_close($CurlObj);
return $Result;
}
If you don’t have an AccessToken and AccessSecret yet, you can get them through the following code:
$OAuthResult=SendTwitterRequest('https://twitter.com/oauth/request_token');
parse_str($OAuthResult, $OauthRet);
if(!isset($OauthRet['oauth_token']))
throw new Exception("OAuth error: $OAuthResult");
$AccessToken=$OauthRet['oauth_token'];
$AccessSecret=$OauthRet['oauth_token_secret'];
Here is an example to pull the last 4 tweets from a user:
$UserName='TheUserName';
$Result=json_decode(SendTwitterRequest('https://api.twitter.com/1.1/statuses/user_timeline.json', Array('screen_name'=>$UserName, 'count'=>4)));
if(isset($Result->{'errors'}))
throw new Exception($Result->{'errors'}[0]->{'message'});
$Tweets=Array();
foreach($Result as $Tweet)
$Tweets[]=$Tweet->text;
print implode('
', $Tweets);
