如何在PHP中發送電子郵件附件

Question

<?php 
    // array with filenames to be sent as attachment 
    $files = array("sendFiles.php"); 

    // email fields: to, from, subject, and so on 
    $to = "dfjdsoj@googlemail.com"; 
    $from = "mail@mail.com"; 
    $subject ="My subject"; 
    $message = "A logo has been sen't by". $_SESSION['loggedin_business_name']; 
    $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/plain; 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  
    echo sizeof($files); 
    $ok = @mail($to, $subject, $message, $headers); 
    if ($ok) { 
     echo "<p>mail sent to $to!</p>"; 
    } else { 
     echo "<p>mail could not be sent!</p>"; 
    } 
    ?> 

我收到一封電子郵件，其中包含我的sendfiles.php，然後是一個文本文件ATT00424.txt。該號碼每次都會更改。發送到我的Gmail，它很好！很奇怪！

$files = array("sendFiles.php"); 

    // email fields: to, from, subject, and so on 

    $to = "hdfiuhufsadhfu@yaho.com"; 

    $from = "mail@mail.com"; 

    $subject ="My subject"; 

    $message = "A logo has been sen't by". $_POST['loggedin_business_name']; 

    $headers = "From: $from"; 

    // boundary 

    $semi_rand = md5(time()); 

    $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; 

// headers for attachment 

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

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

    $message .= "--{$mime_boundary}\r\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)); 

     $message .= "Content-Type: {\"application/octet-stream\"};\r\n" . " name=\"$files[$x]\"\r\n" . 

     "Content-Disposition: attachment;\r\n" . " filename=\"$files[$x]\"\r\n" . 

     "Content-Transfer-Encoding: base64\r\n" . $data . "\r\n"; 

     $message .= "--{$mime_boundary}\r\n"; 

    } 

固定附件問題但是現在「A標誌已被sen't」消息的代碼添加CRLF已經消失了。爲什麼是這樣？

Answer 1

Use phpMailer()

<?php 
require_once('phpmailer.php'); 

$mail = new PHPMailer(true); // the true param means it will throw exceptions on errors, which we need to catch 
$mail->IsSendmail(); // telling the class to use SendMail transport 

try { 
    $mail->AddReplyTo('email@example.com', 'First Last'); 
    $mail->AddAddress('John@example.com', 'John Doe'); 

    $mail->SetFrom('email@example.com', 'First Last'); 
    $mail->Subject = "Subject Line"; 
    $mail->AltBody = "Alternate Text"; // optional, comment out and test 

    $mail->WordWrap  = 50; // set word wrap  
    $mail->Body = "This is the body of the email"; 
    $mail->IsHTML(true); // send as HTML 

    // Single or Multiple File Attachments 
    $mail->AddAttachment('../path-to-file.pdf', 'File-Name.pdf'); 
    $mail->Send(); // Try to send email 
    //echo "Message Sent OK<p></p>\n"; 
    } catch (phpmailerException $e) { 
     echo $e->errorMessage(); //Pretty error messages from PHPMailer 
    } catch (Exception $e) { 
     echo $e->getMessage(); //Boring error messages from anything else! 
} 
// end try 


?> 

Answer 2

嘗試使用CRLF（\ r \ n）換行符。 Outlook對這些事情可能有點有趣。

Answer 3

據我所知，當Outlook使用混合編碼接收部分消息時，Outlook會創建ATT12345.txt附件。如果編碼（或新的MIME部分）發生更改後無法轉換消息的其餘部分，則會將其餘部分轉儲到附件中，並使用您所看到的通用名稱。看起來Gmail似乎比Outlook更好地處理格式（不令人驚訝）。

我不是Outlook專家（絕對不要碰東西），但看起來好像this answer on SO可能會有幫助（在最後一部分之後檢查您的$ mime_boundary變量是否爲' - '）。
