Answer 1

我已经看了评论中的链接，并清理了一些功能。有一件事我使用了一个参数和heredocs的关联数组，因为在示例中使用php标记和输出缓冲并不完全干净（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' 
)); 

您可以从$_FILES沿着文件路径传递到"file"说法。

使用文件上传脚本，就像您可以在互联网上找到的那样（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，只需使用I.devries的评论（http://webcheatsheet.com/php/send_email_text_html_attachment.php）中提及的代码将附件与您的邮件一起发送。

下面你可以从上面提到的网站上找到一些复制粘贴的代码，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"; 
?>
