What are the potential pitfalls of implementing mod_rewrite in PHP?
One potential pitfall of implementing mod_rewrite in PHP is that it can lead to duplicate content issues if not properly handled. This can negatively impact SEO and confuse search engines. To solve this issue, you can use the canonical tag in your HTML to specify the preferred URL for a given page.
// Check if the requested URL is the canonical URL
if ($_SERVER['REQUEST_URI'] !== '/canonical-url') {
// Redirect to the canonical URL
header('Location: /canonical-url', true, 301);
exit();
}
