 # PHPMailer - A full-featured email creation and transfer class for PHP Build status: [](https://travis-ci.org/PHPMailer/PHPMailer) [](https://scrutinizer-ci.com/g/PHPMailer/PHPMailer/) [](https://scrutinizer-ci.com/g/PHPMailer/PHPMailer/) [](https://packagist.org/packages/phpmailer/phpmailer) [](https://packagist.org/packages/phpmailer/phpmailer) [](https://packagist.org/packages/phpmailer/phpmailer) [](https://packagist.org/packages/phpmailer/phpmailer) ## Class Features - Probably the world's most popular code for sending email from PHP! - Used by many open-source projects: WordPress, Drupal, 1CRM, SugarCRM, Yii, Joomla! and many more - Integrated SMTP support - send without a local mail server - Send emails with multiple To, CC, BCC and Reply-to addresses - Multipart/alternative emails for mail clients that do not read HTML email - Add attachments, including inline - Support for UTF-8 content and 8bit, base64, binary, and quoted-printable encodings - SMTP authentication with LOGIN, PLAIN, CRAM-MD5 and XOAUTH2 mechanisms over SSL and SMTP+STARTTLS transports - Validates email addresses automatically - Protect against header injection attacks - Error messages in over 50 languages! - DKIM and S/MIME signing support - Compatible with PHP 5.5 and later - Namespaced to prevent name clashes - Much more! ## Why you might need it Many PHP developers utilize email in their code. The only PHP function that supports this is the `mail()` function. However, it does not provide any assistance for making use of popular features such as HTML-based emails and attachments. Formatting email correctly is surprisingly difficult. There are myriad overlapping RFCs, requiring tight adherence to horribly complicated formatting and encoding rules - the vast majority of code that you'll find online that uses the `mail()` function directly is just plain wrong! *Please* don't be tempted to do it yourself - if you don't use PHPMailer, there are many other excellent libraries that you should look at before rolling your own - try [SwiftMailer](https://swiftmailer.symfony.com/), [Zend/Mail](https://zendframework.github.io/zend-mail/), [eZcomponents](https://github.com/zetacomponents/Mail) etc. The PHP `mail()` function usually sends via a local mail server, typically fronted by a `sendmail` binary on Linux, BSD and OS X platforms, however, Windows usually doesn't include a local mail server; PHPMailer's integrated SMTP implementation allows email sending on Windows platforms without a local mail server. ## License This software is distributed under the [LGPL 2.1](http://www.gnu.org/licenses/lgpl-2.1.html) license. Please read LICENSE for information on the software availability and distribution. ## Installation & loading PHPMailer is available on [Packagist](https://packagist.org/packages/phpmailer/phpmailer) (using semantic versioning), and installation via [Composer](https://getcomposer.org) is the recommended way to install PHPMailer. Just add this line to your `composer.json` file: ```json "phpmailer/phpmailer": "~6.0" ``` or run ```sh composer require phpmailer/phpmailer ``` Note that the `vendor` folder and the `vendor/autoload.php` script are generated by Composer; they are not part of PHPMailer. If you want to use the Gmail XOAUTH2 authentication class, you will also need to add a dependency on the `league/oauth2-client` package in your `composer.json`. Alternatively, if you're not using Composer, copy the contents of the PHPMailer folder into one of the `include_path` directories specified in your PHP configuration and load each class file manually: ```php <?php use PHPMailerPHPMailerPHPMailer; use PHPMailerPHPMailerException; require 'path/to/PHPMailer/src/Exception.php'; require 'path/to/PHPMailer/src/PHPMailer.php'; require 'path/to/PHPMailer/src/SMTP.php'; ``` If you're not using the `SMTP` class explicitly (you're probably not), you don't need a `use` line for the SMTP class. If you don't speak git or just want a tarball, click the 'zip' button on the right of the project page in GitHub, though note that docs and examples are not included in the tarball. ## Legacy versions PHPMailer 5.2 (which is compatible with PHP 5.0 - 7.0) is no longer being supported for feature updates, and will only be receiving security updates from now on. You will find the latest version of 5.2 in the [5.2-stable branch](https://github.com/PHPMailer/PHPMailer/tree/5.2-stable), and future versions of 5.2 will be tagged with 5.2.x version numbers, so existing Composer configs should remain working. If you're using PHP 5.5 or later, we recommend you make the necessary changes to switch to the 6.0 release. ## Upgrading from 5.2 The biggest changes are that source files are now in the `src/` folder, and PHPMailer now declares the namespace `PHPMailerPHPMailer`. This has several important effects – [read the upgrade guide](https://github.com/PHPMailer/PHPMailer/tree/master/UPGRADING.md) for more details. ### Minimal installation While installing the entire package manually or with Composer is simple, convenient and reliable, you may want to include only vital files in your project. At the very least you will need [src/PHPMailer.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/PHPMailer.php). If you're using SMTP, you'll need [src/SMTP.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/SMTP.php), and if you're using POP-before SMTP, you'll need [src/POP3.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/POP3.php). You can skip the [language](https://github.com/PHPMailer/PHPMailer/tree/master/language/) folder if you're not showing errors to users and can make do with English-only errors. If you're using XOAUTH2 you will need [src/OAuth.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/OAuth.php) as well as the Composer dependencies for the services you wish to authenticate with. Really, it's much easier to use Composer! ## A Simple Example ```php <?php // Import PHPMailer classes into the global namespace // These must be at the top of your script, not inside a function use PHPMailerPHPMailerPHPMailer; use PHPMailerPHPMailerException; //Load Composer's autoloader require 'vendor/autoload.php'; $mail = new PHPMailer(true); // Passing `true` enables exceptions try { //Server settings $mail->SMTPDebug = 2; // Enable verbose debug output $mail->isSMTP(); // Set mailer to use SMTP $mail->Host = 'smtp1.example.com;smtp2.example.com'; // Specify main and backup SMTP servers $mail->SMTPAuth = true; // Enable SMTP authentication $mail->Username = 'user@example.com'; // SMTP username $mail->Password = 'secret'; // SMTP password $mail->SMTPSecure = 'tls'; // Enable TLS encryption, `ssl` also accepted $mail->Port = 587; // TCP port to connect to //Recipients $mail->setFrom('from@example.com', 'Mailer'); $mail->addAddress('joe@example.net', 'Joe User'); // Add a recipient
