Best PHP Mail Class

I wrote this class. It works great! You can send just about as many attachments as you like and include HTML in the message. The only bug is that every email looks like there is an attachment. Hope this helps.

class Email {

// Public Variables
public $To = "";
public $Title = "";
public $Message = "";
public $From = "";
public $FromName = "";
public $ReplyTo = "";
public $ReplyToName = "";
public $ReturnPath = "";
public $ReturnPathName = "";
public $Headers = "";

private $Boundry = "";
private $Attachments = array();
private $FinalData = "";
private $EOL = "\r\n";
private $FinalHeaders = "";

* Send - Send Message based on Populated Class Vars
* Will return false, and fail to send message, if required fields are empty.
* @access public
* @return bool True on Success, False on Failure
public function Send() {

if ($this->To && $this->From) {
// Build Email

// SEND IT!!!
return mail( $this->To, $this->Title, $this->FinalData, $this->FinalHeaders );

} else {
throw new Exception('"To" and "From" properties (email addresses) must be set before sending email');


* AttachFile - Include file to be sent as an attachment
* @access public
* @param string $filename
* @param string $contents
* @return bool True on Success, False on Failure
public function AttachFile( $filename, $filetype, $filedata ) {

$this->Attachments[] = new Attachment($filename, $filetype, $filedata);


/* -- Private Functions -- */

* Put the email string all together
* @access private
private function BuildEmail() {
// Set boundary
$this->Boundry = md5(uniqid());

// Build main headers

// Start first boundary
$this->FinalData .= "--".$this->Boundry.$this->EOL;

// Assemble message

// Assemble attachments

* IncludeMessage - Includes message into FinalData string
* @access private
private function IncludeMessage() {
$this->FinalData .= "Content-Type: text/html; charset=\"iso-8859-1\"{$this->EOL}";
$this->FinalData .= "Content-Transfer-Encoding: 7bit".$this->EOL.$this->EOL;
$this->FinalData .= $this->Message.$this->EOL.$this->EOL;
$this->FinalData .= "--".$this->Boundry.$this->EOL;

* IncludeAttachments - Include previously attachmented files into FinalData string
* This method should never be called explicitly, as it is called from within the
* `Send` function.
* @access private
private function IncludeAttachments() {

foreach ($this->Attachments as $attachment) {
$this->FinalData .= "Content-Type: ".$attachment->filetype.$this->EOL;
$this->FinalData .= "Content-Transfer-Encoding: base64".$this->EOL;
$this->FinalData .= "Content-Disposition: attachment; filename=\"{$attachment->filename}\"".$this->EOL.$this->EOL;
$this->FinalData .= chunk_split(base64_encode($attachment->filedata));
$this->FinalData .= "--".$this->Boundry.$this->EOL;


* BuildHeaders - Compile headers from member vars
* This method should never be called explicitly, as it is called from within the
* `Send` function.
* @access private
private function BuildHeaders() {

$headers = "";

// From
if($this->FromName) $headers .= "From: ".$this->FromName." From.">".$this->EOL;
else $headers .= "From: {$this->From}{$this->EOL}";

// Reply-To
if(!$this->ReplyTo) $this->ReplyTo = $this->From;
if($this->ReplyToName) $headers .= "Reply-To: ".$this->ReplyToName." ReplyTo.">".$this->EOL;
else $headers .= "Reply-To: {$this->ReplyTo}{$this->EOL}";

// Return-Path
if(!$this->ReturnPath) $this->ReturnPath = $this->From;
if($this->ReturnPathName) $headers .= "Return-Path: ".$this->ReturnPathName." ReturnPath.">".$this->EOL;
else $headers .= "Return-Path: {$this->ReturnPath}{$this->EOL}";

// Message-ID
$headers .= "Message-ID: ".$this->EOL;

// X-Mailer ... dunno wut foh
$headers .= "X-Mailer: PHP v".phpversion().$this->EOL;

// MIME-Version
$headers .= "MIME-Version: 1.0{$this->EOL}";

// Content-Type, DO NOT CHANGE, must stay for attachments and whatnot
$headers .= "Content-Type: multipart/mixed; boundary=\"{$this->Boundry}\";{$this->EOL}";

// Append additional headers although there probably shouldn't ever be any
$this->FinalHeaders = $headers . $this->Headers;


class Attachment {
public $filename;
public $filetype;
public $filedata;

public function __construct($filename, $filetype, $filedata) {
$this->filename = $filename;
$this->filetype = $filetype;
$this->filedata = $filedata;

    Your posts suck

      You are right. They do suck. But I am going to make this blog much better.

      This PHP class is not that good. I recommend getting PHP Mailer. It sends emails via SMTP through an outbound email server that you have. I use it at work and it is easy to use and setup.

      Sorry for the crappy posts. It’s a work-in-progress.

    Your posts do not suck at all. Question of taste of what you are looking for. Thanks for sharing the class.

      Thank you Laura for the support 😉

      This class actually isn’t that good though. I wrote it a while ago. It causes there to be an empty file attachment in some email clients, namely Yahoo. This class does work though however you have to have sendmail installed on your server.

      Per my post above, I recommend using PHP Mailer however I wrote code which puts emails in a queue which is later called by a script which uses PHP Mailer.

      PHP Mailer uses sockets to connect to the actual email server whom which you are sending thus bypassing any email daemon you may be running on the server. This could cause quite a delay when sending an email. So if you are writing an interface and don’t want lag, I recommend writing one script which puts your email into a database and then call a command script which can be ran in the background to use PHP Mailer to actually send it. By calling a second background script, code execution immediately continues after the command call.
