Lonnie Knows Everything

So you want to post twitter updates and perhaps follow people using PHP but you’re annoyed with that oauth implementation because it makes life difficult? no problem

I’ve constructed a class that implements two functions, posting a status update and following an author .. This is purely for educational purposes and is intended to demonstrate the art of page scraping as well as the use of CURL for posting and retrieving data, I would of course never personally recommend using the code because I’m sure it’s some sort of violation of their TOS ;) so yeah.. don’t do it! ;) ;)

Some important things to note:

1. This will break if twitter changes their html up too much
2. This is probably a violation, so if you do use it, use it reasonably .. don’t submit a million requests per second, throttle it down =)
3. You’re using it at your own risk
4. It will post status updates as if you posted from a mobile device ( Ie. Mobile Web )
