<?php

use \CI_Controller;

class Email extends CI_Controller {

    public function __construct() {
        parent::__construct();
        $this->load->library('email');
    }

    public function send_verification_email($to_email, $verification_code) {
        $this->email->from('your_email@example.com', 'Your Name');
        $this->email->to($to_email);

        $this->email->subject('Email Verification');
        $this->email->message('Please click on the following link to verify your email: ' . base_url('verification/verify/' . $verification_code));

        if ($this->email->send()) {
            return true;
        } else {
            return false;
        }
    }
}

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

use \CI_Controller;

class Verification extends CI_Controller {

    public function __construct() {
        parent::__construct();
        $this->load->model('verification_model');
        $this->load->library('email');
    }

    public function send_verification_email() {
        // 获取要验证的电子邮件和验证码
        $to_email = 'user@example.com';
        $verification_code = '123456';

        // 发送验证电子邮件
        if ($this->email->send_verification_email($to_email, $verification_code)) {
            echo 'Verification email sent successfully.';
        } else {
            echo 'Failed to send verification email.';
        }
    }

    public function verify($verification_code) {
        // 验证电子邮件的逻辑
    }
}

$route['verification/send'] = 'verification/send_verification_email';
$route['verification/verify/(:any)'] = 'verification/verify/$1';
