What are the advantages of hashing IP addresses before storing them in a database, and how can this be implemented in PHP scripts?

Hashing IP addresses before storing them in a database can help protect the privacy and security of users. By hashing the IP addresses, the original values are transformed into a fixed-length string of characters that cannot be easily reversed. This adds a layer of anonymity and prevents the direct identification of individuals based on their IP addresses. 

// Hashing IP address before storing in database
$ip_address = $_SERVER['REMOTE_ADDR'];
$hashed_ip = hash('sha256', $ip_address);

// Store the hashed IP address in the database
// Example query: INSERT INTO users (hashed_ip) VALUES ('$hashed_ip');
