If-Statement in a best way

The CMS Questions

Hello,

I want to check, is not the visited page “Projects”, only then an additional attribute should be in use.
Sorry, i’m not so familiar with PHP and perhaps in a special Kirby approach yet.

I’m looking for something like this:

<?php if ($page() <> page('projects')) : ?> 
<p>Example</p>
<?php endif ?>

Thank you

<?php endif ?>
