How can I ensure data integrity when using $_POST in PHP?
Ensuring data integrity when using $_POST involves several steps:
- Data Validation: Validate all user inputs to ensure they meet the expected format and criteria.
- Data Sanitization: Sanitize inputs to remove any unwanted or potentially harmful characters.
- Use Prepared Statements: For database interactions, use prepared statements to prevent SQL injection attacks.
- Implement CSRF Protection: Use CSRF tokens to ensure that the data is being sent from a legitimate source.
