                           Simplon/Twitter

Intro

What is simplon/twitter?

It's a library which helps you to communicate with twitter's api. In particular it will let you generate access tokens and publish/interact with a tweet.

Any dependencies?

PHP 5.4
CURL

Install

Easy install via composer. Still no idea what composer is? Inform yourself here.

{
    "require": {
        "simplon/twitter": "*"
    }
}

Requirements

In order to interact with twitter's api you need to register your app in order to receive a consumer key and a consumer secret. Register your app at twitter's application management.

Eventually you should receive something similar to the following example:

Consumer key (apiKey): E3yaXX2LvOFXXXXikwMUyvlQD
Consumer secret (apiSecret): WkhXXZPbyFdLiHqDCkSEqJodxm5XdIPLuFNzs1sXXdv09ZXXX7

Request Access Tokens

The following lines will describe how to generate a pair of access tokens which are needed for twitter's api communication. If anything goes wrong a TwitterException will be thrown.

1. Oauth Request Token

Just follow-up with the code below. You should receive a class (OauthRequestTokenVo) which holds among other things an OauthToken. Call Twitter::getAuthenticationUrl() by passing in the mentioned token. As a result you will receive a URL - redirect the user to this url. The user will end up at twitter's authentication page and will grant you permission to access his/her profile.

require __DIR__ . '/vendor/autoload.php';

// your app's consumer tokens
$apiKey = 'E3yaXX2LvOFXXXXikwMUyvlQD';
$apiSecret = 'WkhXXZPbyFdLiHqDCkSEqJodxm5XdIPLuFNzs1sXXdv09ZXXX7';

// where should twitter redirect the user?
$callbackUrl = 'https://yourdomain.com/twitter';

// twitter session with your credentials
$twitter = new \Simplon\Twitter\Twitter($apiKey, $apiSecret);

try
{
    $oauthRequestTokenVo = $twitter->requestOauthRequestToken($callbackUrl);

    echo "Twitter redirect url:\n";
    echo $twitter->getAuthenticationUrl($oauthRequestTokenVo->getOauthToken());
    echo "\n\n";
}
catch (\Simplon\Twitter\TwitterException $e)
{
    var_dump($e->getMessage());
}

2. Oauth Access Token

When the user gave you permissions twitter will redirect to your prior defined callback url by attaching two GET parameters which looks something like the following example: ?oauth_token=AuNV9QXXXXXXelElAAABT0C1Sw4&oauth_verifier=UpVzmg0tiNXXXwuddcmIxgIb5PVuSn.

You will need both parameters to receive the user's profile data and access tokens in order to interact with his/her twitter account. The received data will be passed back as a OauthAccessTokenVo class.

YOU NEED BOTH ACCESS TOKENS: Make sure to save all data away for later use. For instance into a database.

require __DIR__ . '/vendor/autoload.php';

// your app's consumer tokens
$apiKey = 'E3yaXX2LvOFXXXXikwMUyvlQD';
$apiSecret = 'WkhXXZPbyFdLiHqDCkSEqJodxm5XdIPLuFNzs1sXXdv09ZXXX7';

// retrieved params
$oauthToken = 'AuNV9QXXXXXXelElAAABT0C1Sw4';
$oauthVerifier = 'UpVzmg0tiNXXXwuddcmIxgIb5PVuSn';

// twitter session with your credentials
$twitter = new \Simplon\Twitter\Twitter($apiKey, $apiSecret);

try
{
	// retrieve access tokens and profile data from user
	$oauthAccessTokenVo = $twitter->requestOauthAccessToken($oauthToken, $oauthVerifier);
	
	var_dump($oauthAccessTokenVo);
   
   // var_dump result would look something like this:
    
    // class Simplon\Twitter\OauthAccessTokenVo#4 (5) {
	// protected $oauthToken =>
	// string(50) "3197060333-xxxx4chX0Sega3iMF0r55PP96BAGyXXXFTwjpgW"
	// protected $oauthTokenSecret =>
	// string(45) "FeIpfZ1qK4jTaKXXXXTaQAlfny0dFgBV4K15vbnFd3XX"
	// protected $userId =>
	// string(10) "1234567899"
	// protected $screenName =>
	// string(12) "foobar user"
	// protected $xAuthExpires =>
	// string(1) "0"
	// }
}
catch (\Simplon\Twitter\TwitterException $e)
{
    var_dump($e->getMessage());
}

That's all there is. Go ahead and try to interact with twitter's api.

Interacting with Twitter's API

The following examples will show you how to publish, read and to destroy a tweet. Visit twitter's dev center to see all api resources.

Simplon/Twitter supports now as well media uploads. An example can be found at the end of the other examples.

1. Publish a tweet

require __DIR__ . '/vendor/autoload.php';

// your app's consumer tokens
$apiKey = 'E3yaXX2LvOFXXXXikwMUyvlQD';
$apiSecret = 'WkhXXZPbyFdLiHqDCkSEqJodxm5XdIPLuFNzs1sXXdv09ZXXX7';

// user's prior retrieved access tokens
$accessToken = '3197060333-xxxx4chX0Sega3iMF0r55PP96BAGyXXXFTwjpgW';
$accessSecret = 'FeIpfZ1qK4jTaKXXXXTaQAlfny0dFgBV4K15vbnFd3XX';

// twitter session with your credentials
$twitter = new \Simplon\Twitter\Twitter($apiKey, $apiSecret);

try
{
	// bind user account to twitter session
	$twitter->setOauthTokens($accessToken, $accessSecret);
	
	// publish tweet
	$response = $twitter->post('statuses/update', ['status' => 'My first tweet!']);
	
	// should hold all tweet specific data in an array
	var_dump($response); // $response['id'] holds the tweet ID
}
catch (\Simplon\Twitter\TwitterException $e)
{
    var_dump($e->getMessage());
}

2. Read a tweet

You will need a tweet ID in order to load its data.

require __DIR__ . '/vendor/autoload.php';

// your app's consumer tokens
$apiKey = 'E3yaXX2LvOFXXXXikwMUyvlQD';
$apiSecret = 'WkhXXZPbyFdLiHqDCkSEqJodxm5XdIPLuFNzs1sXXdv09ZXXX7';

// user's prior retrieved access tokens
$accessToken = '3197060333-xxxx4chX0Sega3iMF0r55PP96BAGyXXXFTwjpgW';
$accessSecret = 'FeIpfZ1qK4jTaKXXXXTaQAlfny0dFgBV4K15vbnFd3XX';

// twitter session with your credentials
$twitter = new \Simplon\Twitter\Twitter($apiKey, $apiSecret);

try
{
	// bind user account to twitter session
	$twitter->setOauthTokens($accessToken, $accessSecret);
	
	// load tweet data by ID
	$response = $twitter->get('statuses/show/633611781445959680');
	
	// should hold all tweet specific data in an array
	var_dump($response);
}
catch (\Simplon\Twitter\TwitterException $e)
{
    var_dump($e->getMessage());
}

3. Destroy a tweet

You will need a tweet ID in order to destroy it.

require __DIR__ . '/vendor/autoload.php';

// your app's consumer tokens
$apiKey = 'E3yaXX2LvOFXXXXikwMUyvlQD';
$apiSecret = 'WkhXXZPbyFdLiHqDCkSEqJodxm5XdIPLuFNzs1sXXdv09ZXXX7';

// user's prior retrieved access tokens
$accessToken = '3197060333-xxxx4chX0Sega3iMF0r55PP96BAGyXXXFTwjpgW';
$accessSecret = 'FeIpfZ1qK4jTaKXXXXTaQAlfny0dFgBV4K15vbnFd3XX';

// twitter session with your credentials
$twitter = new \Simplon\Twitter\Twitter($apiKey, $apiSecret);

try
{
	// bind user account to twitter session
	$twitter->setOauthTokens($accessToken, $accessSecret);
	
	// destroy tweet by ID
	$response = $twitter->get('statuses/destroy/633611781445959680');
	
	// should hold all tweet specific data in an array
	var_dump($response);
}
catch (\Simplon\Twitter\TwitterException $e)
{
    var_dump($e->getMessage());
}

4. Uploand and tweet an image

require __DIR__ . '/vendor/autoload.php';

// your app's consumer tokens
$apiKey = 'E3yaXX2LvOFXXXXikwMUyvlQD';
$apiSecret = 'WkhXXZPbyFdLiHqDCkSEqJodxm5XdIPLuFNzs1sXXdv09ZXXX7';

// user's prior retrieved access tokens
$accessToken = '3197060333-xxxx4chX0Sega3iMF0r55PP96BAGyXXXFTwjpgW';
$accessSecret = 'FeIpfZ1qK4jTaKXXXXTaQAlfny0dFgBV4K15vbnFd3XX';

// twitter session with your credentials
$twitter = new \Simplon\Twitter\Twitter($apiKey, $apiSecret);

try
{
	// bind user account to twitter session
	$twitter->setOauthTokens($accessToken, $accessSecret);
	
	// upload image
	$response = $twitter->upload('http://example-image.png'); 

	// should hold all media specific data in an array
	var_dump($response); // $response['media_id'] holds the media ID
	
	// publish tweet w/ media
	$response = $twitter->post('statuses/update', ['status' => 'Crazy summer vacation!', 'media_ids' => $response['media_id']);
	
	// should hold all tweet specific data in an array
	var_dump($response); // $response['id'] holds the tweet ID
}
catch (\Simplon\Twitter\TwitterException $e)
{
    var_dump($e->getMessage());
}
