How can I improve the security settings in my PHP application?

You can enhance your PHP application's security by implementing several best practices, such as using prepared statements to prevent SQL injection, validating and sanitizing user inputs, and keeping your PHP version up to date.

What are prepared statements and how do they work?

Prepared statements are a feature of database management systems that allow you to execute the same SQL statement repeatedly with high efficiency. They help prevent SQL injection by separating SQL logic from data.

Are there any specific PHP settings I should configure for better security?

Yes, you should consider settings like disabling display_errors in production, setting session.cookie_httponly to true, and using secure session management practices.

What about file permissions? How should I set them?

File permissions are crucial. Generally, you should set directories to 755 and files to 644. Avoid giving write permissions to the web server user unless absolutely necessary.
