PHP Twitter Timeline Feed: Retrieve the tweets from a user timeline

README

I've written this class to automate the process of authenticating and querying the Twitter APIs.

There are three steps to follow, the first is up to you:
- create a client on Twitter Dev site, just follow the instructions here:
https://dev.twitter.com/oauth/application-only
https://dev.twitter.com/rest/reference/get/statuses/user_timeline

The second and third steps are accomplished by my class and are:
- make a POST request to Twitter Oauth service in order to retrieve an access token; the endpoint is
https://api.twitter.com/oauth2/token

- make a GET request to Twitter API using the access token; you can use any valid endpoint, I'm using
https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=[TWITTER_USERNAME]

That GET request, if correct, returns the json with the feed of the Twitter user passed through screen_name GET variable.

EXAMPLE

After creating a client on Twitter Dev site, you have to use consumer_key and consumer_key_secret provided by the client:

$consumer_key = "CONSUMER_KEY";
$consumer_key_secret = "CONSUMER_KEY_SECRET";

Then create an instance of GetTwitterFeed; the first parameter is the endpoint:

$retrieveUrl = "https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=[TWITTER_USERNAME]";

The second and third parameters are consumer_key and consumer_key_secret

$objTwitter = new GetTwitterFeed($retrieveUrl, $consumer_key, $consumer_key_secret);

If you want to print the raw json, remember to declare correct headers:


header('Access-Control-Allow-Origin: *');
header('Content-Type: application/json');

echo $objTwitter->getJsonFeed();
