That works for me and I can't see anything wrong. But you should check for whitespace on line 7 though. Extra white space can interfere with <<< functionality.
Putting a space at the end of line 7 broke what was working for me just now.

Please mysql is deprecated, try to get used to mysqli or PDO.

thanks but after removing the white space now m getting error like "Parse error: syntax error, unexpected end of file in C:\xampp\htdocs\registration.php on line 20"

<?php
extract($_POST);
include "connection.php";
$link= md5($txtuname);
$str = <<<abc
account is created click on the activation link <a href="http://abc.com/active.php?$link">click</a>
abc;  
if(mysql_query("insert tbl_user values ('$txtuname','$txtpwd','$txtemail','0','$link')"))
{
    echo "registration completed";
    mail($txtemail,"activation link", "$str","from:[e-mail] \r \n contenttype:text/html");
}
else
    {
        if(mysql_error()==1062)
        {
        echo "username exist";
        }
    }
?>

I think the <<<abc abc in the $str is causing the error. Please use this

$str = "Account is created click on the activation link <a href=\"http://abc.com/active.php?$link\">Click</a>";
