How can PHP developers ensure that ICQ numbers are securely stored in a database when implementing ICQ support?

To ensure that ICQ numbers are securely stored in a database when implementing ICQ support, PHP developers should hash the ICQ numbers before storing them. This adds an additional layer of security by converting the ICQ numbers into a fixed-length string of characters that cannot be easily reversed. By hashing the ICQ numbers, even if the database is compromised, the original ICQ numbers cannot be easily obtained. 

// Hashing the ICQ number before storing it in the database
$icqNumber = "123456789";
$hashedICQ = password_hash($icqNumber, PASSWORD_DEFAULT);

// Storing the hashed ICQ number in the database
$stmt = $pdo->prepare("INSERT INTO users (icq_number) VALUES (:icq_number)");
$stmt->bindParam(':icq_number', $hashedICQ);
$stmt->execute();
