A library of PHP classes that provide auto-linking and extraction of usernames, lists, hashtags and URLs from tweets. Originally created from twitter-text-rb and twitter-text-java projects by Matt Sanford and ported to PHP by Mike Cochrane, this library has been improved and made more complete by Nick Pope.

• Add links to all matching Twitter usernames (no account verification).
• Add links to all user lists (of the form @username/list-name).
• Add links to all valid hashtags.
• Add links to all URLs.
• Support for international character sets.

• Extract mentioned Twitter usernames (from anywhere in the tweet).
• Extract replied to Twitter usernames (from start of the tweet).
• Extract all user lists (of the form @username/list-name).
• Extract all valid hashtags.
• Extract all URLs.
• Support for international character sets.

• Highlight text specifed by a range by surrounding with a tag.
• Support for highlighting when tweet has already been autolinked.
• Support for international character sets.

For examples, please see tests/example.php which you can view in a browser or run from the command line.

You'll need the test data which is in YAML format from the following repository:

http://github.com/mzsanford/twitter-text-conformance

It has already been added as a git submodule so you should just need to run:

git submodule init
git submodule update

As PHP has no native support for YAML you'll need to checkout spyc from svn into tests/spyc:

svn checkout http://spyc.googlecode.com/svn/trunk/ tests/spyc

There are a couple of options for testing conformance:

1. Run phpunit in from the root folder of the project.
2. Run tests/runtests.php from the command line.
3. Make tests/runtests.php accessible on a web server and view it in your browser.

The bulk of this library is from the heroic efforts of:

• Mike Cochrane (https://github.com/mikenz): For the original code
• Nick Pope (https://github.com/ngnpope): For the bulk of the maintenance work to date.
