Blog url is appended to all anchor tags on the wordpress blog hosted on different ser

If my blog url is and it is wordpress blog hosted on different server then I have added this code to my sidebar in a php code widget:

// Your twitter username.
$username = “example”;
// Prefix - some text you want displayed before your latest tweet.
// (HTML is OK, but be sure to escape quotes with backslashes: for example href=\“link.html\”)
$prefix = “”;
// Suffix - some text you want display after your latest tweet. (Same rules as the prefix.)
$suffix = “”;
$feed = “” . $username . “&rpp=1”;
function parse_feed($feed) {
$stepOne = explode(“<content type=\“html\”>”, $feed);
$stepTwo = explode(“</content>”, $stepOne[1]);
$tweet = $stepTwo[0];
$tweet = str_replace(“<”, “<”, $tweet);
$tweet = str_replace(“>”, “>”, $tweet);
return $tweet;
$twitterFeed = file_get_contents($feed);
echo parse_feed($twitterFeed);

<a href=“” title=“Follow me on Twitter”><strong>Follow me on Twitter</strong></a>

Now what happens is when the tweet is displayed, instead of showing the handle for eg. it shows like this: which is wrong. Please if anybody knows whats going wrong, I need some help.
