To handle form submissions securely with $_POST, consider the following practices:
- Use HTTPS: Ensure that your form is submitted over HTTPS to encrypt data in transit.
- Validate and sanitize inputs: Always validate and sanitize data using functions like
filter_varandhtmlspecialcharsto prevent security vulnerabilities. - Use prepared statements: For database interactions, use prepared statements to prevent SQL injection.
- Implement CSRF protection: Use tokens to protect against Cross-Site Request Forgery. You can generate and validate CSRF tokens using PHP sessions.
