You should consider using a PHP mail library such as PHPMailerwhich would make the procedure to send mail much simpler and better.
您应该考虑使用 PHP 邮件库，例如PHPMailer，这将使发送邮件的过程更加简单和更好。
Here's an example of how to use PHPMailer, it's really simple!
这里有一个PHPMailer的使用例子，真的很简单！
<?php
require_once('../class.phpmailer.php');
$mail = new PHPMailer(); // defaults to using php "mail()"
$body = file_get_contents('contents.html');
$body = eregi_replace("[\]",'',$body);
$mail->AddReplyTo("[email protected]","First Last");
$mail->SetFrom('[email protected]', 'First Last');
$mail->AddReplyTo("[email protected]","First Last");
$address = "[email protected]";
$mail->AddAddress($address, "John Doe");
$mail->Subject = "PHPMailer Test Subject via mail(), basic";
$mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test
$mail->MsgHTML($body);
$mail->AddAttachment("images/phpmailer.gif"); // attachment
$mail->AddAttachment("images/phpmailer_mini.gif"); // attachment
if(!$mail->Send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
echo "Message sent!";
}
?>

Simple answer: Don't do it. building a MIME email by hand is a painful business, and VERY easy to screw up.
简单的回答：不要这样做。手动构建 MIME 电子邮件是一项痛苦的工作，而且很容易搞砸。
Instead, use PHPMaileror Swiftmailer. It's almost trivial to do attachments with them, and you get FAR FAR FAR better feedback in case something does blow up, v.s. the simple true/false that mail() condescends to spit out.
相反，请使用PHPMailer或Swiftmailer。用它们做附件几乎是微不足道的，你会得到更好的反馈，以防万一发生问题，而不是 mail() 屈尊吐出的简单的真/假。

To eliminate deprecation errors,
为了消除弃用错误，
Replace
代替
$body = eregi_replace("[\]",'',$body);
With
和
$body = preg_replace('/\.([^\.]*$)/i','',$body);
