What potential pitfalls should be avoided when implementing password hashing in PHP?

One potential pitfall to avoid when implementing password hashing in PHP is using outdated or insecure hashing algorithms like MD5 or SHA1. It is recommended to use stronger algorithms like bcrypt or Argon2 for better security. Additionally, make sure to properly salt the passwords before hashing to prevent rainbow table attacks. 

// Using bcrypt hashing algorithm with salt
$password = "password123";
$salt = random_bytes(16); // Generate a random salt
$hashed_password = password_hash($password, PASSWORD_BCRYPT, ['salt' => $salt]);

// Verify password
if (password_verify($password, $hashed_password)) {
    echo "Password is correct";
} else {
    echo "Password is incorrect";
}
