Trouble creating a PHP string

Question

I have a database driven website. There is a basic template that is the format for each page. There are various parts that need to change for each different page. One line for an example is this.

 <link rel="canonical" href="http://mywebsite.com/details.php?id=1" />

I changed the line code to this and stills it works fine and does exactly what I wanted it to do.

<link rel="canonical" href="<?php echo "$record->canonical";?>" />

The problem I am having is, when the cell is empty I am printing this line which is not need if the quotes are blank. How can I remove this line when the cell in my database is empty?

<link rel="canonical" href="" />

could you give more detail about $record->canonical can you share the page code ? — Ahmet ATAK

<?php if ($record->canonical != ""): ?>
<link rel="canonical" href="<?php echo $record->canonical ?>" />
<?php endif ?>

<?php 
echo($record->canonical != "" ? $record->canonical : '');
?>

Which is the same as if $record->canonical is not "" (after the ?-sign) echo it, otherwise (after the :-sign) echo nothing ( '' ).
