使用PHP在邮件中发送附件

请使用PHPMailer,这将很容易将其集成到您的应用程序中。

从以下位置下载PHPMailer脚本: http://github.com/PHPMailer/PHPMailer

提取存档并复制 src 将文件夹放置到项目中方便的位置。

现在,发送带有附件的电子邮件非常简单:

require 'phpmailer/src/PHPMailer.php';

use PHPMailer\PHPMailer\PHPMailer;

$email = new PHPMailer();
$email->From      = 'you@example.com';
$email->FromName  = 'Your Name';
$email->Subject   = 'Message Subject';
$email->Body      = $bodytext;
$email->addAddress('destination@example.com');

$email->addAttachment('PATH_TO_YOUR_FILE_HERE');

return $email->send();

只有一句话: $email->addAttachment();

                            //plain text 
                            $body = "--$boundary\r\n";
                            $body .= "Content-Type: text/plain; charset=ISO-8859-1\r\n";

                    }

$sentMail = @mail($recipient_email, $subject, $body, $headers);
                        if($sentMail) //output success or failure messages
                        {       
                            echo 'Thank you for your email';
                        }else{
                            die('Could not send mail.');  
                        }

您可以简单地将邮件功能置于循环之外?尝试上述代码。请忽略语法错误,因为我没有测试它。但你可以遵循逻辑。

使现代化

核心PHP中的工作脚本,用于在一封邮件中发送多个附件。

<?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;
    }
}
?>
