In what ways can the use of outdated password hashing methods, such as md5, impact the security of user data in PHP applications?

Using outdated password hashing methods like md5 can significantly impact the security of user data in PHP applications because these methods are no longer considered secure due to their vulnerability to brute force attacks and rainbow table attacks. To improve security, it is recommended to use stronger hashing algorithms like bcrypt or Argon2. 

// Using bcrypt for password hashing
$options = [
    'cost' => 12,
];
$password = 'password123';
$hashed_password = password_hash($password, PASSWORD_BCRYPT, $options);

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