php怎样发送html格式邮件-乐工具技术知识

要使用PHP发送HTML格式的电子邮件，您可以使用PHPMailer这样的库。以下是使用PHPMailer发送HTML邮件的步骤：

首先，确保已经安装了PHPMailer库。如果还没有安装，可以使用composer进行安装：

composer require phpmailer/phpmailer

创建一个新的PHP文件，例如send_html_email.php，并在文件中包含autoload文件以及初始化PHPMailer类：



配置SMTP服务器设置：

try {
    //Server settings
    $mail->SMTPDebug = 2;               // Enable verbose debug output
    $mail->isSMTP();                    // Send using SMTP
    $mail->Host       = 'smtp_host';     // Set the SMTP server to send through
    $mail->SMTPAuth   = true;          // Enable SMTP authentication
    $mail->Username   = 'your_username'; // SMTP username
    $mail->Password   = 'your_password'; // SMTP password
    $mail->SMTPSecure = 'tls';        // Enable implicit TLS encryption
    $mail->Port       = 587;            // TCP port to connect to; use 465 if you have set `SMTPSecure = phpseclib::ENCRYPTION_STARTTLS`


设置发件人、收件人以及邮件内容：

    //Recipients
    $mail->setFrom('your_email@example.com', 'Mailer');
    $mail->addAddress('recipient@example.com', 'Joe User');     // Add a recipient

    // Content
    $mail->isHTML(true);                                 // Set email format to HTML
    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'This is the HTML message body in bold!';
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';


发送邮件并检查结果：

    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}


完整的代码示例：

SMTPDebug = 2;               // Enable verbose debug output
    $mail->isSMTP();                    // Send using SMTP
    $mail->Host       = 'smtp_host';     // Set the SMTP server to send through
    $mail->SMTPAuth   = true;          // Enable SMTP authentication
    $mail->Username   = 'your_username'; // SMTP username
    $mail->Password   = 'your_password'; // SMTP password
    $mail->SMTPSecure = 'tls';        // Enable implicit TLS encryption
    $mail->Port       = 587;            // TCP port to connect to; use 465 if you have set `SMTPSecure = phpseclib::ENCRYPTION_STARTTLS`

    //Recipients
    $mail->setFrom('your_email@example.com', 'Mailer');
    $mail->addAddress('recipient@example.com', 'Joe User');     // Add a recipient

    // Content
    $mail->isHTML(true);                                 // Set email format to HTML
    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'This is the HTML message body in bold!';
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
?>

将上述代码中的smtp_host、your_username、your_password、your_email@example.com、recipient@example.com等值替换为您自己的SMTP服务器设置和电子邮件地址。运行此PHP脚本，如果一切配置正确，收件人应该会收到一封包含HTML内容的电子邮件。
