What are the potential security risks of using less secure hashing algorithms like MD5 for password storage in PHP?

Using less secure hashing algorithms like MD5 for password storage in PHP can pose a significant security risk because these algorithms are no longer considered secure due to their vulnerability to brute force attacks and collisions. It is recommended to use more secure algorithms like bcrypt or Argon2 for password hashing in PHP to ensure the protection of user credentials. 

// Using bcrypt for secure password hashing
$options = [
    'cost' => 12,
];

$password = 'password123';
$hashed_password = password_hash($password, PASSWORD_BCRYPT, $options);

// Verify password
if (password_verify($password, $hashed_password)) {
    echo 'Password is valid!';
} else {
    echo 'Invalid password.';
}
