How can one ensure the security and proper functioning of URL manipulation in PHP scripts through htaccess rules and RewriteRules?

URL manipulation in PHP scripts can be secured and properly managed using htaccess rules and RewriteRules. By creating rules in the htaccess file, you can redirect and rewrite URLs to ensure they are clean, user-friendly, and secure. This can help prevent malicious attacks such as SQL injection or cross-site scripting.

RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ index.php?page=$1 [L]
