A PHP Mailer Class - Abu Ashraf Masnun

UPDATE: Added application of the basename() function to the attached filenames to get the filenames only.

This php class lets you attach multiple files and send emails via Postfix without digging into the messy headers 😀

<?php
class Mailer {
    function __construct($to="",$from="",$sub="",$msg="",$files=array()) {
        $this->to = $to;
        $this->from = $from;
        $this->sub = $sub;
        $this->msg = $msg;
        $this->files = $files;
    }

    function attachFile($file) {
        if(!empty($file)) {
            $this->files[] = $file;
        }
    }


    function setMessage($msg) {
        if(!empty($msg)) {
            $this->msg = $msg;
        }
    }


    function setTo($to) {
        if(!empty($to)) {

    function setSubject($sub) {
        if(!empty($sub)) {
            $this->sub = $sub;
        }
    }

$m->setTo("maSnun <masnun@gmail.com>");
$m->setFrom("phpGeek <masnun@leevio.com>");
$m->setSubject("A bunch of files");
$m->setMessage("Hello buddy! Files attached!");
$m->attachFile("images/Screenshot.png");

if($m->sendMail()) { echo "Sent \n"; } else { echo "failed \n"; }
?>

<?php

include("mailer.php");

$m = new Mailer();

$m->setTo("maSnun <masnun@gmail.com>");

$m->setFrom("phpGeek <masnun@leevio.com>");

$m->setSubject("A bunch of files");

$m->setMessage("Hello buddy! Files attached!");

$m->attachFile("images/Screenshot.png");

if($m->sendMail()) { echo "Sent \n"; } else { echo "failed \n"; }
