Include multiple attachment by mail PHP - php

Question

First of all, I know there are many library out there to do what I want to do, mainly PHPMailer and SwiftMailer.
For some reason, those two are not working with my server.
So here I am doing it from scratch.
I've found this code on the PHP documentation which is working quite fine, I would like to know how to tweak the code in order to send multiple files instead of one.
Here the code:
<?php
echo date("H:i:s");
echo mail::sendMail("to#domain.com", "Test Attach ". date("H:i:s"), "Contenu du mail <a href=3D'domain.com'>domain.com</a>", __FILE__, "xx#domain.com",'' , true);
?>
source :
<?php
class mail {
public static function prepareAttachment($path) {
$rn = "\r\n";
if (file_exists($path)) {
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$ftype = finfo_file($finfo, $path);
$file = fopen($path, "r");
$attachment = fread($file, filesize($path));
$attachment = chunk_split(base64_encode($attachment));
fclose($file);
$msg = 'Content-Type: \'' . $ftype . '\'; name="' . basename($path) . '"' . $rn;
$msg .= "Content-Transfer-Encoding: base64" . $rn;
$msg .= 'Content-ID: <' . basename($path) . '>' . $rn;
// $msg .= 'X-Attachment-Id: ebf7a33f5a2ffca7_0.1' . $rn;
$msg .= $rn . $attachment . $rn . $rn;
return $msg;
} else {
return false;
}
}
public static function sendMail($to, $subject, $content, $path = '', $cc = '', $bcc = '', $_headers = false) {
$rn = "\r\n";
$boundary = md5(rand());
$boundary_content = md5(rand());
// Headers
$headers = 'From: Mail System PHP <no-reply#domain.com>' . $rn;
$headers .= 'Mime-Version: 1.0' . $rn;
$headers .= 'Content-Type: multipart/related;boundary=' . $boundary . $rn;
//adresses cc and ci
if ($cc != '') {
$headers .= 'Cc: ' . $cc . $rn;
}
if ($bcc != '') {
$headers .= 'Bcc: ' . $cc . $rn;
}
$headers .= $rn;
// Message Body
$msg = $rn . '--' . $boundary . $rn;
$msg.= "Content-Type: multipart/alternative;" . $rn;
$msg.= " boundary=\"$boundary_content\"" . $rn;
//Body Mode text
$msg.= $rn . "--" . $boundary_content . $rn;
$msg .= 'Content-Type: text/plain; charset=ISO-8859-1' . $rn;
$msg .= strip_tags($content) . $rn;
//Body Mode Html
$msg.= $rn . "--" . $boundary_content . $rn;
$msg .= 'Content-Type: text/html; charset=ISO-8859-1' . $rn;
$msg .= 'Content-Transfer-Encoding: quoted-printable' . $rn;
if ($_headers) {
$msg .= $rn . '<img src=3D"cid:template-H.PNG" />' . $rn;
}
//equal sign are email special characters. =3D is the = sign
$msg .= $rn . '<div>' . nl2br(str_replace("=", "=3D", $content)) . '</div>' . $rn;
if ($_headers) {
$msg .= $rn . '<img src=3D"cid:template-F.PNG" />' . $rn;
}
$msg .= $rn . '--' . $boundary_content . '--' . $rn;
//if attachement
if ($path != '' && file_exists($path)) {
$conAttached = self::prepareAttachment($path);
if ($conAttached !== false) {
$msg .= $rn . '--' . $boundary . $rn;
$msg .= $conAttached;
}
}
//other attachement : here used on HTML body for picture headers/footers
if ($_headers) {
$imgHead = dirname(__FILE__) . '/../../../../modules/notification/ressources/img/template-H.PNG';
$conAttached = self::prepareAttachment($imgHead);
if ($conAttached !== false) {
$msg .= $rn . '--' . $boundary . $rn;
$msg .= $conAttached;
}
$imgFoot = dirname(__FILE__) . '/../../../../modules/notification/ressources/img/template-F.PNG';
$conAttached = self::prepareAttachment($imgFoot);
if ($conAttached !== false) {
$msg .= $rn . '--' . $boundary . $rn;
$msg .= $conAttached;
}
}
// Fin
$msg .= $rn . '--' . $boundary . '--' . $rn;
// Function mail()
mail($to, $subject, $msg, $headers);
}
}
?>
Where it says: FILE that where I've put the file name.
How do I do it so I can put more than one file.
Thank you.

Using the mail() for attachments is a little more complex than that. You got to tell mail() which part should handle the file attachment and which part is responsible to display the email body by setting up a MIME Boundary. In other words, the code should be divided into 2 parts:
A section to handle the message being sent in body
A section to handle file uploading

However, I would suggest you to use a very handy tool called PHPMailer to do the same task. It simplifies the process and lets the class handle all the legwork.
