PHP邮件发送代码 - 使用sendmail函数发送邮件

This is PHP code for sending emails using the sendmail function. To use it, you need to provide the recipient's email address, the email subject, and the email content. If the email is sent successfully, it will return '成功' (success), otherwise it will return '失败' (failure).

To use the code, replace the placeholder values in the example with your own values:

if (send_mali('recipient@example.com','Subject','<p>Content</p>')) {
    echo '成功';
} else {
    echo '失败';
}

Make sure to include the 'sendmail.php' file before using the function.
