How can PHP developers implement password salting to enhance the security of user passwords?

To enhance the security of user passwords, PHP developers can implement password salting. Password salting involves adding a random string of characters to each user's password before hashing it. This makes it harder for attackers to crack passwords using precomputed rainbow tables or dictionary attacks. 

// Generate a random salt
$salt = bin2hex(random_bytes(16));

// Combine the user's password with the salt
$saltedPassword = $password . $salt;

// Hash the salted password using a secure hashing algorithm like bcrypt
$hashedPassword = password_hash($saltedPassword, PASSWORD_BCRYPT);

// Store the hashed password and salt in the database
// Remember to store the salt along with the hashed password for verification
