Drogyn's suggestion would work too, but it's not quite as clean.
However, Russell's example might not work for you because, when your variable is an element of an array, you need to concatinate it like this:
<?php echo "User"; ...note that the variable is inside of ". and ." Or you can put the variable in {} like: echo "User"; But the way Russel showed you would work if you were using a simple variable like: echo "User";
OR
<?php echo "Read more..."; OR <a href="template.php?aid=<?php echo $aid; ?>">Read more...</a>
