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）。然后你就有了一些临时文件，我们称之为file_to_send。然后只需使用 I.devries 评论中提到的代码（ http://webcheatsheet.com/php/ send_email_text_html_attachment.php ）用于将附件与邮件一起发送。

您可以在下面找到一些从上述站点复制粘贴的代码，但进行了必要的调整。

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 = '[email protected]'; 
//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: [email protected]\r\nReply-To: [email protected]"; 
//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"; 
?>

我查看了评论中的链接，并将一些内容清理到了函数中。一方面，我使用了参数和此处文档的关联数组，因为示例中 php 标签和输出缓冲的使用并不完全干净（或者不像 PHP 那样干净）。

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

emailFile(array(
    'to' => '[email protected]',
    'from' => '[email protected]',
    '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" 参数中。
