(Top posting fixed)
Just like any other PHP statements - you need it within <?php and ?>.
In this case you want to display the value, so you echo it, i.e.
<a href="http://www.widgets.com/<?php echo $var;?>">click here </a>
Also,
<?=$var?>
is not good. It depends on short tags being on, and it isn't in a lot
(most?) hosts nowadays. The echo above works on any system.
And please don't top post. Thanks.
