What potential issue is highlighted in the use of md5 for password comparison in the PHP code?

The potential issue with using md5 for password comparison in PHP is that it is considered insecure due to its vulnerability to brute force attacks and rainbow table attacks. To solve this issue, it is recommended to use a more secure hashing algorithm, such as bcrypt, which is specifically designed for securely hashing passwords. 

// Hash the password using bcrypt
$hashed_password = password_hash($password, PASSWORD_BCRYPT);

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