What is a captive portal?

There are many definitions out there which are explaining about captive portal like in TechTarget SearchMobileComputing, Answers.com, and Wikipedia. Still haven't got it?

If you have your own blog which is PHP powered, you can show your tweets on twitter by using PHP easily. According to GET Search Twitter API documentation and Using Search documentation, we can do any search for tweets related to any keyword provided. The resource URL for searching is:

http://search.twitter.com/search.format

where format is the format we would like to get. It could be rss, atom, or even json. The Twitter search API is very powerful, even you can get any tweets which is posted by someone near you.
