Routines for reading a user's Twitter timeline and rendering results to HTML5 markup.

PHP Twitter utility classes

PHP classes for reading a user's timeline and rendering the results to valid HTML5 markup. Built against the current (as of March 2014) Twitter REST API v1.1 which has now superseded the disabled v1.0 API.

• Requires
• Twitter\UserTimeline()
• Twitter\HTMLMarkup()
• Example

Requires

• PHP 5.5 (using Generators for working over timelines).
• cURL for HTTP calls.

Twitter\UserTimeline()

Allows reading of a user's timeline via the REST API v1.1 GET statuses/user_timeline method and parsing the returned JSON tweet data into usable PHP array structures.

A basic usage example:

<?php
require('twitter/usertimeline.php');
$userTimeline = new Twitter\UserTimeline(
	'API_KEY',
	'API_SECRET',
	'ACCESS_TOKEN',
	'ACCESS_TOKEN_SECRET',
	'TWITTER_SCREEN_NAME'
);

$userTimeline->setExtendedTweetMode(true);
$userTimeline->setFetchBatchSize(50);

$fetchCount = 0;

foreach ($userTimeline->resultList() as $resultItem) {
	print_r($resultItem);

	/*
	Array
	(
		[ID] => 448276129489506304 // 64bit integer
		[created] => 1395712332 // unix timestamp
		[userID] => 26228734
		[userFullName] => Peter Mescalchin
		[userScreenName] => magnetikonline
		[text] => Packaged up my PHP classes on GitHub for reading Twitter user timelines via the v1.1 API and marking up to nice HTML https://t.co/97rrSunyrk
		[replyToID] => // note: false if NOT a reply
		[replyToUserID] => // note: false if NOT a reply
		[replyToUserScreenName] => // note: false if NOT a reply
		[retweetCreated] => // note: false if NOT a retweet
		[entityList] => Array
			(
				[0] => Array
					(
						[type] => url
						[indices] => Array
							(
								[0] => 117
								[1] => 140
							)

						[text] => https://t.co/97rrSunyrk
						[url] => https://github.com/magnetikonline/phptwitterclasses
					)

			)

	)
	*/

	if ($fetchCount++ > 5) {
		break;
	}
}

• In order to make OAuth 1.0a API requests to Twitter you need a set of API access tokens. These can be generated against your Twitter user account at https://apps.twitter.com/.
• The Twitter\UserTimeline()->resultList() method has been implemented as a PHP generator to lazy load the Twitter timeline in batches (up to a current maximum of 3200 tweets).
  • Batch fetch size can be controlled via the Twitter\UserTimeline()->setFetchBatchSize(SIZE) method (defaulting to 10 items).
• Twitter\UserTimeline()->resultList() accepts an optional $sinceTweetID parameter, which will tell the API to only fetch tweets more recent than the given tweet ID.
• By default the API will return classic 140 character tweet responses, automatically truncating longer 280 character tweets to maintain backward compatibility.
  • To return full length tweets, use the Twitter\UserTimeline()->setExtendedTweetMode() method.
• API v1.1 introduced the concept of entities for Tweets which gives a collection of external resources associated to a tweet. Types returned here will be one of:
  • hashtag.
  • url.
  • user (user mention).
  • media (Twitter photo upload).
• The OAuth 1.0a routines used internally have been bundled up into a set of fairly easy to use private functions which should make it simple to extend this with further API method calls if desired. The Twitter API documentation provides a step by step breakdown to the OAuth request generation process required.

Twitter\HTMLMarkup()

Takes a data structure emitted by Twitter\UserTimeline()->resultList() above and generates a valid HTML5 representation of the tweet.

Simple example:

<?php
require('twitter/htmlmarkup.php');
$resultItem = $userTimeline->resultList()->current();
$HTMLMarkup = new Twitter\HTMLMarkup();
$HTMLMarkup->setURLMaxDisplayLength(50);

echo($HTMLMarkup->execute($resultItem));

... will produce (wrapped for readability):

	and marking up to nice HTML
	<a class="url"
		href="https://github.com/magnetikonline/phptwitterclasses"
		title="https://github.com/magnetikonline/phptwitterclasses">

	</a>
</p>

• Twitter\HTMLMarkup->execute() uses the returned tweet entities to generate anchor tags within the content. Each anchor will have a class assigned of hashtag, url, user and media.
• Anchor types of hashtag and user will have their respective text wrapped in <span class="text"> elements to allow removal of anchor hover underlines for the preceding @ and # characters via CSS to match default Twitter styling. Example:
  • <a class="hashtag" href="twitter.com/search">#<span class="text">hashtag</span></a>
  • <a class="user" href="twitter.com/username">@<span class="text">username</span></a>
• Displayed truncation of long URLs can be controlled with the Twitter\HTMLMarkup->setURLMaxDisplayLength() method (default of 20 characters). Set false to disable truncation.

Example

See the provided example.php for a demo of fetching a total of five tweets, emitting the PHP array structure of each and marking up the result as HTML5.
