How to connect to the Alibaba Cloud email push interface through PHP to implement the email sending function

Alibaba Cloud Email Push is an efficient and real-time email sending service that can help developers quickly implement the email sending function. In this article, we will introduce how to use PHP to connect to the Alibaba Cloud email push interface to implement the email sending function.

First, we need to activate the email push service in the Alibaba Cloud console and obtain the AccessKeyId and AccessKeySecret for identity authentication.

Next, we can create a new PHP file, named "mailer.php", and introduce the Alibaba Cloud Mail Push SDK, which can be installed through Composer. The specific installation command is as follows:

composer require alibabacloud/push-mailer

In the "mailer.php" file, we can write the following code:

<?php

use AlibabaCloudClientAlibabaCloud;
use AlibabaCloudClientExceptionClientException;
use AlibabaCloudClientExceptionServerException;
use AlibabaCloudClientResultResult;

require_once 'vendor/autoload.php';

// 设置AccessKeyId和AccessKeySecret
AlibabaCloud::accessKeyClient('your_access_key_id', 'your_access_key_secret')
    ->regionId('cn-hangzhou')
    ->asDefaultClient();

/**
 * 发送邮件
 * @param string $toEmail 接收邮件的地址
 * @param string $subject 邮件主题
 * @param string $content 邮件内容
 * @return Result
 */
function sendEmail($toEmail, $subject, $content)
{
    try {
        // 调用SendMail接口发送邮件
        $result = AlibabaCloud::rpc()
            ->product('Dm')
            ->version('2015-11-23')
            ->action('SingleSendMail')
            ->method('POST')
            ->host('dm.aliyuncs.com')
            ->options([
                'query' => [
                    'RegionId' => 'cn-hangzhou',
                    'AccountName' => 'noreply@example.com',
                    'ReplyToAddress' => 'false',
                    'AddressType' => '1',
                    'ToAddress' => $toEmail,
                    'Subject' => $subject,
                    'HtmlBody' => $content,
                ],
            ])
            ->request();

        return $result;
    } catch (ClientException $e) {
        echo $e->getMessage() . PHP_EOL;
    } catch (ServerException $e) {
        echo $e->getMessage() . PHP_EOL;
    }
}

In the above code, we first set the AccessKeyId and AccessKeySecret, and specify the region as "cn-hangzhou". Then, we defined a

sendEmail()

function, which receives the recipient’s email address, email subject, and email content as parameters, and calls the ## of Alibaba Cloud Email Push SDK #SingleSendMail Interface to send emails. Among the interface parameters, we need to pass in information such as the sender's address, whether to enable the reply function, address type, recipient's address, email subject, and email content. Finally, we can call the sendEmail()

function in other PHP files to implement the email sending function. For example:

require_once 'mailer.php';

$toEmail = 'recipient@example.com';
$subject = '这是一封测试邮件';
$content = '<h1>欢迎使用阿里云邮件推送服务！</h1>';

$result = sendEmail($toEmail, $subject, $content);

if ($result instanceof Result) {
    // 发送成功
    echo '邮件发送成功！' . PHP_EOL;
} else {
    // 发送失败
    echo '邮件发送失败！' . PHP_EOL;
}

In the above code, we introduced the "mailer.php" file and called the sendEmail() function to send the email. After the sending is successful, "E-mail sent successfully!" will be output; after the sending fails, "E-mail sent failed!" will be output.

The above are the steps for using PHP to connect to the Alibaba Cloud email push interface to implement the email sending function. By using the Alibaba Cloud email push service, we can quickly and reliably implement the email sending function to provide a better user experience for our applications.
