title: Getting posted data from remote url
body: <p>I am using PHP and Apache Server and I want values to be get posted to a url. </p>
  
  <p>For eg. The remote server will post instant message data to my domain which is like "<a href="http://www.example.com/getdata/" rel="nofollow">http://www.example.com/getdata/</a>" and I will get this posted data from the url and save it to the database. 
  What could be the best possible solution for achieving this? Do I need to use a web service?</p>
