Can any body tell me how to share Url or content of a site by PHP on Blogger and Tumblr as how we can share on Facebook with
<a href="http://www.facebook.com/sharer.php?u=sitename/pagabc" target="blank"><img src="images/fbshare.png" /></a>
or Twitter
<a href="http://twitter.com/share?text=TestText&url=sitename/pagabc" target="_blank"><img src="images/twittershare.png" /></a>
