What are common misconceptions about linking in PHP and HTML?

Common misconceptions about linking in PHP and HTML include using absolute paths instead of relative paths, not properly escaping special characters in URLs, and forgetting to include the necessary file extensions. To solve these issues, always use relative paths for links within your website, use functions like urlencode() to properly escape special characters in URLs, and make sure to include the correct file extensions for linked files.

<!-- Incorrect way of linking using absolute path -->
<a href="http://www.example.com/page.php">Link</a>

<!-- Correct way of linking using relative path -->
<a href="page.php">Link</a>
