The anchor tag you gave as an example just loops back to the same page, it’s an infinite loop.
For example if the page is called index.php then
[php]Continue[/php]
is the same thing as this
[php]Continue[/php]
The only real reason you would want to do this way is to make the script portable, I would get in a habit of doing the other way. One it looks nicer and two it gives you or someone else looking at the code more information in what you’re trying to do when you come across it in the future.
if you want to go to a different page you would have to treat it as you would a normal anchor tag:
[php]Continue[/php]
