I am developing a website for a small company and have added the copyright for their company and next to it saying it was designed by my company.
The HTML code:
<p>Copyright © 2012 Teguise Broker | Designed by <?php include 'copyright.php'; ?></p>
The PHP code:
<?php echo "<a href='http://www.my-company.org'>My Company</a>"; ?>
What I want to do is try and make the HTML code non-removable or if they do try to remove it, the page doesn't display. Help would be really appreciated.
There is no way to absolutely stop them if they have access to the source code. The best you can do is make it difficult for them to remove it. A PHP obfuscator would be the best way to complicate it for them. But see this answer for why you shouldn't bother.
