Proof if (re)tweeted (Pay with a tweet)

[unityinsider]

Hello guys,

how can I check on my PHP Script if someone (re)tweeted my tweet (e.g. “Get 50% discout @account on http://www.site.com”)?

I want to make kind of a Fan-Gate on Facebook which shows two parts of content.
First content for non-retweeters and second content for those who already tweeted it.

Is there a tutorial or something like that?

I know this tool:

But this looks very unprofessional…

Thanks!

The best way to accomplish this is with the User Streams streaming API. Instead of checking after the fact whether someone retweeted your tweet, you would be streamed information on retweets in real time as they happen.
