如何连接两个或多个文件，并在PHP

Question

发送邮件下面的代码只发送一个附件，但我需要连接和发送两个文件（一个RAR文件和PDF）

$email_to = "$email"; // The email you are sending to (example) 
$email_from = "online@example.co.in"; // The email you are sending from (example) 
$email_subject = "subject line"; // The Subject of the email 
$email_txt = "text body of message"; // Message that the email has in it 
$fileatt = "files/example.rar"; // Path to the file (example) 
$fileatt_type = "application/x-rar-compressed"; // File Type 
$fileatt_name = "example.rar"; // Filename that will be used for the file as the attachment 
$file = fopen($fileatt,'rb'); 
$data = fread($file,filesize($fileatt)); 
fclose($file); 
$semi_rand = md5(time()); 
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; 
$headers="From: $email_from"; // Who the email is from (example) 
$headers .= "\nMIME-Version: 1.0\n" . 
"Content-Type: multipart/mixed;\n" . 
" boundary=\"{$mime_boundary}\""; 
$email_message .= "This is a multi-part message in MIME format.\n\n" . 
"--{$mime_boundary}\n" . 
"Content-Type:text/html; charset=\"iso-8859-1\"\n" . 
"Content-Transfer-Encoding: 7bit\n\n" . $email_txt; 
$email_message .= "\n\n"; 
$data = chunk_split(base64_encode($data)); 
$email_message .= "--{$mime_boundary}\n" . 
"Content-Type: {$fileatt_type};\n" . 
" name=\"{$fileatt_name}\"\n" . 
"Content-Transfer-Encoding: base64\n\n" . 
$data . "\n\n" . 
"--{$mime_boundary}--\n"; 

mail($email_to,$email_subject,$email_message,$headers); 

Answer 1

继reusability principles，你可以使用https://github.com/Synchro/PHPMailer

<?php 
require 'PHPMailerAutoload.php'; 

$mail = new PHPMailer; 

$mail->isSMTP();          // Set mailer to use SMTP 
$mail->Host = 'smtp1.example.com;smtp2.example.com'; // Specify main and backup server 
$mail->SMTPAuth = true;        // Enable SMTP authentication 
$mail->Username = 'jswan';       // SMTP username 
$mail->Password = 'secret';       // SMTP password 
$mail->SMTPSecure = 'tls';       // Enable encryption, 'ssl' also accepted 

$mail->From = 'from@example.com'; 
$mail->FromName = 'Mailer'; 
$mail->addAddress('josh@example.net', 'Josh Adams'); // Add a recipient 
$mail->addAttachment('/var/tmp/file.tar.gz');   // Add attachments 
$mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name        

$mail->Subject = 'Here is the subject'; 
$mail->Body = 'This is the HTML message body <b>in bold!</b>'; 
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients'; 

if(!$mail->send()) { 
    echo 'Message could not be sent.'; 
    echo 'Mailer Error: ' . $mail->ErrorInfo; 
    exit; 
} 

echo 'Message has been sent'; 

Answer 2

试试看。把数组中的文件，然后使用一个循环的形式添加的每个人在$email_message可变

$email_to = "$email"; // The email you are sending to (example) 
$email_from = "online@example.co.in"; // The email you are sending from (example) 
$email_subject = "subject line"; // The Subject of the email 
$email_message = "text body of message"; // Message that the email has in it 
$files = array("file_1.ext","file_2.ext","file_3.ext",......); 
$semi_rand = md5(time()); 
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; 
$headers="From: $email_from"; // Who the email is from (example) 
$headers .= "\nMIME-Version: 1.0\n" . 
"Content-Type: multipart/mixed;\n" . 
" boundary=\"{$mime_boundary}\""; 
$email_message .= "This is a multi-part message in MIME format.\n\n" . 
"--{$mime_boundary}\n" . 
"Content-Type:text/html; charset=\"iso-8859-1\"\n" . 
"Content-Transfer-Encoding: 7bit\n\n" . $email_txt; 
$email_message .= "\n\n"; 
    for($x=0;$x<count($files);$x++){ 
    $file = fopen($files[$x],"rb"); 
    $data = fread($file,filesize($files[$x])); 
    fclose($file); 
    $data = chunk_split(base64_encode($data)); 
    $email_message .= "Content-Type: {\"application/octet-stream\"};\n" . " name=\"$files[$x]\"\n" . 
    "Content-Disposition: attachment;\n" . " filename=\"$files[$x]\"\n" . 
    "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n"; 
    $email_message .= "--{$mime_boundary}\n"; 
    } 

mail($email_to,$email_subject,$email_message,$headers); 

希望它工作得很好:)

这是我用来发送多个附件的代码，我希望这也能帮助你。您实际上需要在附加多个文件时使用循环。

$files = array("file1.pdf","file2.pdf"); 
    $body = "email in html form"; 

    // email fields: to, from, subject, and so on 
    $to = "e-mail id of person you are sending to"; 
    $from = "your e-mail id"; 
    $subject = "email subject"; 
    $message = html_entity_decode($body); 
    $headers = "From: $from"; 

    // boundary 
    $semi_rand = md5(time()); 
    $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; 

    // headers for attachment 
    $headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary=\" {$mime_boundary}\""; 

    // multipart boundary 
    $message = "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type: text/html; charset=\"iso-8859-1\"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $message . "\n\n"; 
    $message .= "--{$mime_boundary}\n"; 

    // preparing attachments 
    for ($x = 0; $x < count($files); $x++) { 
     $file = fopen($files[$x], "rb"); 
     $data = fread($file, filesize($files[$x])); 
     fclose($file); 
     $data = chunk_split(base64_encode($data)); 
     $message .= "Content-Type: {\"application/octet-stream\"};\n" . " name=\"$files[$x]\"\n" . 
      "Content-Disposition: attachment;\n" . " filename=\"$files[$x]\"\n" . 
      "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n"; 
     $message .= "--{$mime_boundary}\n"; 
    } 

    // send 

    $ok = @mail($to, $subject, $message, $headers); 
    if ($ok) { 
     echo "<p>mail sent to $to!</p>"; 
    } else { 
     echo "<p>mail could not be sent!</p>";

简单的工作和测试，例如：

<?php 
    mail_attachment("mail@mail.com","Subject","Here is the body",array("file1.pdf","file2.pdf")); 
    function mail_attachment($to, $subject, $message, $files) { 
     $headers = "From: no-reply@mail.com"; 
     $semi_rand = md5(time()); 
     $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; 
     $headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary=\"{$mime_boundary}\""; 

     $message = "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type: text/html; charset=\"iso-8859-1\"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $message . "\n\n"; 
     $message .= "--{$mime_boundary}\n"; 

     foreach ($files as $file) { 

     $filename = end(explode("/",$file)); 
     $data = file_get_contents($file); 

     $data = chunk_split(base64_encode($data)); 

     $message .= "Content-Type: {\"application/octet-stream\"};\n" . " name=\"$file\"\n" . 
      "Content-Disposition: attachment;\n" . " filename=\"$file\"\n" . 
      "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n"; 
     $message .= "--{$mime_boundary}\n"; 
     } 
     echo (@mail($to, $subject, $message, $headers)) ? "<p>Send to $to!</p>" : "<p>Not send toaar $to!</p>"; 
    } // mail-attachment 
?>

检查PHP核心邮件功能以下多个文件附件。

<?php 
/** Mail with attachment */ 
function mail_attachment($filename, $path, $mailto, $from_mail, $from_name, $replyto, $bcc, $subject, $message){  
    $uid = md5(uniqid(time())); 
    $mime_boundary = "==Multipart_Boundary_x{$uid}x"; 

    $header = "From: ".$from_name." <".$from_mail.">\r\n"; 
    $header .= "Bcc: ".$bcc."\r\n"; 
    $header .= "Reply-To: ".$replyto."\r\n"; 
    $header .= "MIME-Version: 1.0\r\n"; 
    $header .= "Content-Type: multipart/mixed; boundary=\"".$mime_boundary."\"\r\n\r\n"; 
    $header .= "This is a multi-part message in MIME format.\r\n"; 
    $header .= "--".$mime_boundary."\r\n"; 
    $header .= "Content-type:text/html; charset=iso-8859-1\r\n"; 
    $header .= "Content-Transfer-Encoding: 7bit\r\n\r\n"; 
    $header .= nl2br($message)."\r\n\r\n"; 
    $header .= "--".$mime_boundary."\r\n"; 

    foreach($filename as $k=>$v){ 

     $file = $path.$v; 
     $file_size = filesize($file); 
     $handle = fopen($file, "r"); 
     $content = fread($handle, $file_size); 
     fclose($handle); 
     $content = chunk_split(base64_encode($content)); 

     $header .= "Content-Type: application/octet-stream; name=\"".$v."\"\r\n"; // use different content types here 
     $header .= "Content-Transfer-Encoding: base64\r\n"; 
     $header .= "Content-Disposition: attachment; filename=\"".$v."\"\r\n\r\n"; 
     $header .= $content."\r\n\r\n"; 
     $header .= "--".$mime_boundary."--"."\r\n"; 
    } 

    if (mail($mailto, $subject, "", $header)) { 
     //echo "mail send ... OK"; // or use booleans here 
     return true; 
    } else { 
     //echo "mail send ... ERROR!"; 
     return false;

这是我获得多个邮件附件和测试成功的最佳解决方案之一。

此代码通过附加电子邮件中的文件而不需要上传到您的托管服务器空间，为您提供了自由。这是非常需要的。

有很多的解决方案，告诉如何将文件上传到服务器，然后发送到电子邮件，但这种解决方案提供了从原来的“直接多个文件附件的电子邮件”

Answer 9

FYI，这条线帖子以及一些答案，会在某些电子邮件系统上造成问题。

$ headers。=“\ nMIME-Version：1.0 \ n”。

\ n在开始时导致附件在发送到托管在emailpros.com上的地址时失败，该地址是一个安全的HIPAA兼容电子邮件系统。简单地删除换行解决了那里的问题。但是，发送到Gmail帐户和另一台主机（Hostmonster）时它一直工作得很好。 这种方式在所有这些方面工作得很好。 $ headers。=“MIME-Version：1.0 \ n”。
