Swiftmailer是另一个易于使用的脚本，可以自动防止电子邮件注入，使附件变得轻而易举。我也强烈反对使用PHP内置的mail()函数。

使用方法:

下载Swiftmailer，并将lib文件夹放在你的项目中 使用require_once 'lib/swift_required.php'包含主文件;

现在当你需要邮寄时添加代码:

// Create the message
$message = Swift_Message::newInstance()
    ->setSubject('Your subject')
    ->setFrom(array('webmaster@mysite.com' => 'Web Master'))
    ->setTo(array('receiver@example.com'))
    ->setBody('Here is the message itself')
    ->attach(Swift_Attachment::fromPath('myPDF.pdf'));

//send the message          
$mailer->send($message);

更多信息和选项可以在Swiftmailer文档中找到。

您可以尝试使用以下代码:

    $filename = 'myfile';
    $path = 'your path goes here';
    $file = $path . "/" . $filename;

    $mailto = 'mail@mail.com';
    $subject = 'Subject';
    $message = 'My message';

    $content = file_get_contents($file);
    $content = chunk_split(base64_encode($content));

    // a random hash will be necessary to send mixed content
    $separator = md5(time());

    // carriage return type (RFC)
    $eol = "\r\n";

    // main header (multipart mandatory)
    $headers = "From: name <test@test.com>" . $eol;
    $headers .= "MIME-Version: 1.0" . $eol;
    $headers .= "Content-Type: multipart/mixed; boundary=\"" . $separator . "\"" . $eol;
    $headers .= "Content-Transfer-Encoding: 7bit" . $eol;
    $headers .= "This is a MIME encoded message." . $eol;

    // message
    $body = "--" . $separator . $eol;
    $body .= "Content-Type: text/plain; charset=\"iso-8859-1\"" . $eol;
    $body .= "Content-Transfer-Encoding: 8bit" . $eol;
    $body .= $message . $eol;

    // attachment
    $body .= "--" . $separator . $eol;
    $body .= "Content-Type: application/octet-stream; name=\"" . $filename . "\"" . $eol;
    $body .= "Content-Transfer-Encoding: base64" . $eol;
    $body .= "Content-Disposition: attachment" . $eol;
    $body .= $content . $eol;
    $body .= "--" . $separator . "--";

    //SEND Mail
    if (mail($mailto, $subject, $body, $headers)) {
        echo "mail send ... OK"; // or use booleans here
    } else {
        echo "mail send ... ERROR!";
        print_r( error_get_last() );
    }

为更多的可读性在一些电子邮件提供商 使用

$body .= $eol。美元的消息。eol美元。eol美元;而且 $body .= $eol。美元的内容。eol美元。eol美元;

工作理念:

if (isset($_POST['submit'])) {
    $mailto = $_POST["mailTo"];
    $from_mail = $_POST["fromEmail"];
    $replyto = $_POST["fromEmail"];
    $from_name = $_POST["fromName"];
    $message = $_POST["message"];
    $subject = $_POST["subject"];

    $filename = $_FILES["fileAttach"]["name"];
    $content = chunk_split(base64_encode(file_get_contents($_FILES["fileAttach"]["tmp_name"])));

    $uid = md5(uniqid(time()));
    $name = basename($file);
    $header = "From: " . $from_name . " <" . $from_mail . ">\r\n";
    $header .= "Reply-To: " . $replyto . "\r\n";

    $header .= "MIME-Version: 1.0\r\n";
    $header .= "Content-Type: multipart/mixed; boundary=\"" . $uid . "\"\r\n\r\n";
    $header .= "This is a multi-part message in MIME format.\r\n";
    $header .= "--" . $uid . "\r\n";

// You add html "Content-type: text/html; charset=utf-8\n" or for Text "Content-type:text/plain; charset=iso-8859-1\r\n" by I.khan
    $header .= "Content-type:text/html; charset=utf-8\n";
    $header .= "Content-Transfer-Encoding: 7bit\r\n\r\n";

// User Message you can add HTML if You Selected HTML content
    $header .= "<div style='color: red'>" . $message . "</div>\r\n\r\n";

    $header .= "--" . $uid . "\r\n";
    $header .= "Content-Type: application/octet-stream; name=\"" . $filename . "\"\r\n"; // use different content types here
    $header .= "Content-Transfer-Encoding: base64\r\n";
    $header .= "Content-Disposition: attachment; filename=\"" . $filename . "\"\r\n\r\n"; // For Attachment
    $header .= $content . "\r\n\r\n";
    $header .= "--" . $uid . "--";
    if (mail($mailto, $subject, "", $header)) {
        echo "<script>alert('Success');</script>"; // or use booleans here
    } else {
        echo "<script>alert('Failed');</script>";
    }
}

HTML代码:

<form enctype="multipart/form-data" method="POST" action=""> 
    <label>Your Name <input type="text" name="sender_name" /> </label> 
    <label>Your Email <input type="email" name="sender_email" /> </label> 
    <label>Your Contact Number <input type="tel" name="contactnumber" /> </label>
    <label>Subject <input type="text" name="subject" /> </label> 
    <label>Message <textarea name="description"></textarea> </label> 
    <label>Attachment <input type="file" name="attachment" /></label> 
    <label><input type="submit" name="button" value="Submit" /></label> 
</form> 

PHP代码:

<?php
if($_POST['button']){
{
    //Server Variables
    $server_name = "Your Name";
    $server_mail = "your_mail@domain.com";

    //Name Attributes of HTML FORM
    $sender_email = "sender_email";
    $sender_name = "sender_name";
    $contact = "contactnumber";
    $mail_subject = "subject";
    $input_file = "attachment";
    $message = "description";

    //Fetching HTML Values
    $sender_name = $_POST[$sender_name];
    $sender_mail = $_POST[$sender_email];
    $message = $_POST[$message];
    $contact= $_POST[$contact];
    $mail_subject = $_POST[$mail_subject];

    //Checking if File is uploaded
    if(isset($_FILES[$input_file])) 
    { 
        //Main Content
        $main_subject = "Subject seen on server's mail";
        $main_body = "Hello $server_name,<br><br> 
        $sender_name ,contacted you through your website and the details are as below: <br><br> 
        Name : $sender_name <br> 
        Contact Number : $contact <br> 
        Email : $sender_mail <br> 
        Subject : $mail_subject <br> 
        Message : $message.";

        //Reply Content
        $reply_subject = "Subject seen on sender's mail";
        $reply_body = "Hello $sender_name,<br> 
        \t Thank you for filling the contact form. We will revert back to you shortly.<br><br>

//#############################DO NOT CHANGE ANYTHING ABOVE THIS LINE#############################

        //Output
        if ($retval == true) {

在与格式糟糕的附件斗争了一段时间后，我使用了以下代码:

$email = new PHPMailer();
$email->From      = 'from@somedomain.com';
$email->FromName  = 'FromName';
$email->Subject   = 'Subject';
$email->Body      = 'Body';
$email->AddAddress( 'to@somedomain.com' );
$email->AddAttachment( "/path/to/filename.ext" , "filename.ext", 'base64', 'application/octet-stream' );
$email->Send();
