Here are some best practices for protecting your website when using PHP:

1. Use the latest version of PHP: Keeping your PHP version up-to-date is crucial for security. Newer versions often include security patches and updates that can help protect your website from vulnerabilities.

2. Sanitize user input: One common vulnerability in PHP websites is SQL injection attacks, where malicious code is injected into input fields. To prevent this, always sanitize user input before using it in your code.

3. Use secure passwords: Always use strong, unique passwords for your database and server. Avoid using common passwords or default passwords, as these are easy targets for hackers.

4. Implement HTTPS: Using HTTPS encryption helps protect the data transmitted between your website and users. This is especially important for e-commerce websites or any site that collects sensitive information.

5. Use secure coding practices: Follow best practices for secure coding, such as avoiding eval() and other potentially dangerous functions, using prepared statements for database queries, and avoiding storing sensitive information in cookies.

6. Set up firewalls and security plugins: Consider using a web application firewall or security plugin to protect your website from common attacks, such as DDoS attacks or cross-site scripting.

7. Regularly update plugins and libraries: Keep all plugins and libraries used in your PHP website up-to-date to ensure they are not vulnerable to known security issues.

8. Monitor and log activity: Set up monitoring and logging tools to track any suspicious activity on your website. This can help you identify and respond to security threats quickly.

9. Backup your website regularly: In case of a security breach or data loss, having regular backups of your website can help you quickly restore your site and minimize downtime.

By following these best practices and staying up-to-date on the latest security trends, you can help protect your PHP website from potential threats and attacks. Remember, website security is a continuous process, so it’s important to regularly review and update your security measures to stay one step ahead of cyber threats.
