    PHP Mail Function Header Format

    What type of headers have to be added in the mail function to attach a file?

    Well, you could get all into multi-part MIME headers, message boundary strings, etc., or do what I do: use a 3rd-party library/class like PHPMailer or SwiftMailer, and let it handle the grunt work. For example: http://phpmailer.worxware.com/index.php?pg=exampleamail

    Below shows to build an e-mail script with attachment function.

    function mail_attachment($filename, $path, $mailto, $from_mail, $from_name, $replyto, $subject, $message) {
    $file = $path.$filename;
    $file_size = filesize($file);
    $handle = fopen($file, "r");
    $content = fread($handle, $file_size);
    $content = chunk_split(base64_encode($content));
    $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";
    $header .= "Content-type:text/plain; charset=iso-8859-1\r\n";
    $header .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
    $header .= $message."\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";
    $header .= $content."\r\n\r\n";
    $header .= "--".$uid."--";
    if (mail($mailto, $subject, "", $header)) {
    echo "mail send ... OK"; // or use booleans here
    } else {
    echo "mail send ... ERROR!";

    Next is to use this function to send an e-mail message with one attached zip file:

    $my_file = "somefile.zip";
    $my_path = $_SERVER['DOCUMENT_ROOT']."/your_path_here/";
    $my_name = "Olaf Lederer";
    $my_mail = "my@mail.com";
    $my_replyto = "my_reply_to@mail.net";
    $my_subject = "This is a mail with attachment.";
    $my_message = "Hallo,\r\ndo you like this script? I hope it will help.\r\n\r\ngr. Olaf";
    mail_attachment($my_file, $my_path, "recipient@mail.org", $my_mail, $my_name, $my_replyto, $my_subject, $my_message);
