I am using this and ( with out using PHPMailer ), Hope this is helpful to you.

<form enctype="multipart/form-data" method="POST" action="">
    <label>Your Name <input type="text" name="sender_name" /> </label> <br>
    <label>Your Email <input type="email" name="sender_email" /> </label> <br>
    <label>Subject <input type="text" name="subject" /> </label> <br>
    <label>Message <textarea name="message"></textarea> </label> <br>
    <label>Attachment <input type="file" name="my_file" /></label><br>
    <label><input type="submit" name="button" value="Submit" /></label>
</form>

<?php 
echo "<pre>";print_r($_REQUEST);echo "</pre>"; //comment this line
echo "<pre>";print_r($_FILES);echo "</pre>"; //comment this line
if($_POST && isset($_FILES['my_file']))
{

    $from_email         = 'noreply@your_domain.com'; //from mail, it is mandatory with some hosts
    $recipient_email    = '[e-mail]'; //recipient email (most cases it is your personal email)

    //Capture POST data from HTML form and Sanitize them, 
    $sender_name    = filter_var($_POST["sender_name"], FILTER_SANITIZE_STRING); //sender name
    $reply_to_email = filter_var($_POST["sender_email"], FILTER_SANITIZE_STRING); //sender email used in "reply-to" header
    $subject        = filter_var($_POST["subject"], FILTER_SANITIZE_STRING); //get subject from HTML form
    //$message        = filter_var($_POST["message"], FILTER_SANITIZE_STRING); //message
    $message        = "Name : ".$sender_name."\nMessage : ".$_POST["message"]; //message

    //Get uploaded file data
    $file_tmp_name    = $_FILES['my_file']['tmp_name'];
    $file_name        = $_FILES['my_file']['name'];
    $file_size        = $_FILES['my_file']['size'];
    $file_type        = $_FILES['my_file']['type'];
    $file_error       = $_FILES['my_file']['error'];

    if($file_error > 0)
    {
        die('Upload error or No files uploaded');
    }
    //read from the uploaded file & base64_encode content for the mail
    $handle = fopen($file_tmp_name, "r");
    $content = fread($handle, $file_size);
    fclose($handle);
    $encoded_content = chunk_split(base64_encode($content));

        $boundary = md5("sanwebe");
        //headers
        $headers = "MIME-Version: 1.0\r\n"; 
        $headers .= "From:".$from_email."\r\n"; 
        $headers .= "Reply-To: ".$reply_to_email."" . "\r\n";
        $headers .= "Content-Type: multipart/mixed; boundary = $boundary\r\n\r\n"; 

        //body plain text 
        $body = "--$boundary\r\n";
        $body .= "Content-Type: text/plain; charset=ISO-8859-1\r\n";
        $body .= "Content-Transfer-Encoding: base64\r\n\r\n"; 
        $body .= chunk_split(base64_encode($message)); 

        //attachment file
        $body .= "--$boundary\r\n";
        $body .="Content-Type: $file_type; name=".$file_name."\r\n";
        $body .="Content-Disposition: attachment; filename=".$file_name."\r\n";
        $body .="Content-Transfer-Encoding: base64\r\n";
        $body .="X-Attachment-Id: ".rand(1000,99999)."\r\n\r\n"; 
        $body .= $encoded_content; 
    $sentMail = @mail($recipient_email, $subject, $body, $headers);
    if($sentMail) //output success or failure messages
    {       
        die('Thank you for your email');
    }else{
        die('Could not send mail!');  
    }
}
?>

for what reason no use phpmailer? example for an attachment:

function mandaMail ($nombredest, $maildest, $asunto, $cuerpo) {
require_once("mailer/class.phpmailer.php");
$mail = new PHPMailer(true);
$mail->IsSMTP();

try {
    $mail->Host = "xxxx"; $mail->Port = 25; // smtp server
    $mail->SMTPAuth = true;
    $mail->Username = "xxxx"; // smtp username
    $mail->Password = "xxxx"; // smtp pass
    $mail->AddReplyTo("xxxx", "xxxx"); // email & name
    $mail->SetFrom("xxxx", "xxxx"); // similar to up value

    $mail->AddAddress($maildest, $nombredest);
    $mail->Subject = $asunto;
    $mail->MsgHTML(file_get_contents($cuerpo));

    $mail->AddAttachment("xxxx", "xxxx"); // attachments directory, attachment name (ie: dir/blah.jpg, blah.jpg)
    $mail->Send();

} catch (phpmailerException $e) { echo $e->errorMessage();
} catch (Exception $e) { echo $e->getMessage(); }

Answer 3

Your code wont be work, because email doesnt support whitespaces.

  $output = "
       --PHP-mixed-$random_hash;
       Content-Type: multipart/alternative; boundary='PHP-alt-$random_hash'
       --PHP-alt-$random_hash
       Content-Type: text/plain; charset='iso-8859-1'
       Content-Transfer-Encoding: 7bit

You must use without whitespaces

 $output = "
 --PHP-mixed-$random_hash;
 Content-Type: multipart/alternative; boundary='PHP-alt-$random_hash'
 --PHP-alt-$random_hash
 Content-Type: text/plain; charset='iso-8859-1'
 Content-Transfer-Encoding: 7bit

Answer 4

You can either do it the way this tutorial describes, or you can use one of the PEAR modules to send an email with an attachment the way this tutorial describes.

Using PEAR is probably a better option as it's easier to do. The only caveat is that PEAR isn't available on all hosts.

I'm using this :

function attachfile($file, $type = "application/octetstream")  {
    if(!($fd = fopen($file, "r"))) {
      $this->errstr = "Error opening $file for reading.";
      return 0;
    }
    $_buf = fread($fd, filesize($file));
    fclose($fd);

    $fname = $file;
    for($x = strlen($file); $x > 0; $x--)
      if($file[$x] == "/")
        $fname = substr($file, $x, strlen($file) - $x);

    // Convert to base64 becuase mail attachments are not binary safe.
    $_buf = chunk_split(base64_encode($_buf));

    $this->attachments[$file] = "\n--" . $this->boundary . "\n";
    $this->attachments[$file] .= "Content-Type: $type; name=\"$fname\"\n";
    $this->attachments[$file] .= "Content-Transfer-Encoding: base64\n";
    $this->attachments[$file] .= "Content-Disposition: attachment; " .
                                     "filename=\"$fname\"\n\n";
    $this->attachments[$file] .= $_buf;

    return 1;
  }
