PHP and PHPMAILER: How to implement email sending function in the website?

As an important part of modern website development, the email sending function is very important in many scenarios. Whether it is user registration, password retrieval, order confirmation or marketing promotion, information needs to be transmitted through email. PHP and PHPMailer are two powerful tools that can help us implement the email sending function in the website.

PHP is a server-side scripting language that can be used to develop various dynamic websites and web applications. PHPMailer is a third-party library based on PHP that can easily send emails. Below we will introduce how to use PHP and PHPMailer to implement the email sending function.

First, we need to install and configure PHPMailer. PHPMailer can be installed through Composer. Composer is a PHP package management tool that can help us manage and load third-party libraries. In the composer.json file in the project root directory, add the following content:

{
    "require": {
        "phpmailer/phpmailer": "6.1.7"
    }
}

Then run the composer install command in the command line, Composer will automatically download and Install the PHPMailer library and its dependencies.

Next, we start writing PHP code to implement the email sending function. First, introduce the PHPMailer class file and create an instance of PHPMailer:

use PHPMailerPHPMailerPHPMailer;
use PHPMailerPHPMailerSMTP;
use PHPMailerPHPMailerException;

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

Next, we need to perform some basic configurations on PHPMailer, including setting up the mail server, filling in the authentication information, etc. The following is a basic configuration example:

$mail->isSMTP();                                            // 使用SMTP协议发送邮件
$mail->Host       = 'smtp.example.com';                      // 设置SMTP服务器地址
$mail->SMTPAuth   = true;                                   // 开启SMTP身份验证
$mail->Username   = 'your-email@example.com';                // SMTP用户名
$mail->Password   = 'your-password';                         // SMTP密码
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;          // 使用STARTTLS加密连接
$mail->Port       = 587;                                    // SMTP服务器端口号

In actual use, we need to replace the SMTP server address, SMTP username and password in the above example to ensure that it matches the actual mail server information.

Next, we can start to set the sender, recipient, subject and body of the email:

$mail->setFrom('sender@example.com', 'Sender');              // 设置发送者邮箱和姓名
$mail->addAddress('recipient@example.com', 'Recipient');     // 添加收件人邮箱和姓名
$mail->Subject = '邮件主题';                                   // 设置邮件主题
$mail->Body    = '邮件正文';                                   // 设置邮件正文

Among them, the setFrom method is used to set the sender Email address and name, the addAddress method is used to add the recipient's email address and name, the Subject attribute is used to set the email subject, and the Body attribute is used to set the email body.

Finally, we send the email by calling the send method:

$mail->send();

If the sending is successful, this method will not have any output. If the sending fails, you can get the reason for the failure by catching the exception:

try {
    $mail->send();
    echo '邮件发送成功！';
} catch (Exception $e) {
    echo '邮件发送失败：' . $mail->ErrorInfo;
}

The above are the basic steps to use PHP and PHPMailer to implement the email sending function. Of course, you can also configure more parameters and expand functions according to actual needs, such as adding attachments, using SMTP proxy servers, etc.

To sum up, PHP and PHPMailer provide powerful and easy-to-use functions, which can easily implement the email sending function in the website. By learning and mastering the use of PHP and PHPMailer, we can better meet the email communication needs in website development. In practical applications, we need to flexibly use these two tools according to specific situations to improve the user experience and functional integrity of the website.
