Answer 1

我已经查看了评论中的链接，并将一些内容清理成了一个功能。首先，我使用了一个关联的参数数组和heredocs，因为在这个例子中使用php标签和输出缓冲并不是完全干净的（或者像PHP一样干净）。

http://aramk.com/php/php-sending-an-email-attachment/

emailFile(array(
    'to' => 'your@email.com',
    'from' => 'my@email.com',
    'subject' => 'Some Subject',
    'message' => '<b>Hello!</b>',
    'plain ' => 'Get a new email client!',
    'file' => '/path/to/file'
));

您可以将文件路径从$_FILES传递到"file"参数。

使用您可以在互联网上找到的文件上传脚本（例如http://www.w3schools.com/php/php_file_upload.asp）。然后你有一些临时文件，我们称之为file_to_send。然后使用I.devries（http://webcheatsheet.com/php/send_email_text_html_attachment.php）评论中提到的代码将附件与您的邮件一起发送。

您可以在下面找到上述网站中的一些复制粘贴代码，但需要进行必要的调整。

HTML：

<form action="upload_file.php" method="post" enctype="multipart/form-data">
    <label for="file_to_send">Filename:</label>
    <input type="file" name="file_to_send" id="file_to_send"><br>
    <input type="submit" name="submit" value="Submit">
</form>

PHP：

<?php 
//define the receiver of the email 
$to = 'youraddress@example.com'; 
//define the subject of the email 
$subject = 'Test email with attachment'; 
//create a boundary string. It must be unique 
//so we use the MD5 algorithm to generate a random hash 
$random_hash = md5(date('r', time())); 
//define the headers we want passed. Note that they are separated with \r\n 
$headers = "From: webmaster@example.com\r\nReply-To: webmaster@example.com"; 
//add boundary string and mime type specification 
$headers .= "\r\nContent-Type: multipart/mixed; boundary=\"PHP-mixed-".$random_hash."\""; 
//read the atachment file contents into a string,
//encode it with MIME base64,
//and split it into smaller chunks
$attachment = chunk_split(base64_encode(file_get_contents($_FILES['file_to_send']['tmp_name']))); 
//define the body of the message. 
ob_start(); //Turn on output buffering 
?> 
--PHP-mixed-<?php echo $random_hash; ?>  
Content-Type: multipart/alternative; boundary="PHP-alt-<?php echo $random_hash; ?>" 

--PHP-alt-<?php echo $random_hash; ?>  
Content-Type: text/plain; charset="iso-8859-1" 
Content-Transfer-Encoding: 7bit

Hello World!!! 
This is simple text email message. 

--PHP-alt-<?php echo $random_hash; ?>  
Content-Type: text/html; charset="iso-8859-1" 
Content-Transfer-Encoding: 7bit

<h2>Hello World!</h2> 
<p>This is something with <b>HTML</b> formatting.</p> 

--PHP-alt-<?php echo $random_hash; ?>-- 

--PHP-mixed-<?php echo $random_hash; ?>  
Content-Type: application/zip; name="attachment.zip"  
Content-Transfer-Encoding: base64  
Content-Disposition: attachment  

<?php echo $attachment; ?> 
--PHP-mixed-<?php echo $random_hash; ?>-- 

<?php 
//copy current buffer contents into $message variable and delete current output buffer 
$message = ob_get_clean(); 
//send the email 
$mail_sent = @mail( $to, $subject, $message, $headers ); 
//if the message is sent successfully print "Mail sent". Otherwise print "Mail failed" 
echo $mail_sent ? "Mail sent" : "Mail failed"; 
?>
