## Why you might need it
+Many PHP developers need to send email from their code. The only PHP function that supports this is [`mail()`](https://www.php.net/manual/en/function.mail.php). However, it does not provide any assistance for making use of popular features such as encryption, authentication, HTML messages, and attachments.
-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, Zend_Mail, eZcomponents 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.

## Installation & loading
-
-PHPMailer is available via [Composer/Packagist](https://packagist.org/packages/phpmailer/phpmailer) (using semantic versioning), so just add this line to your `composer.json` file:
+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": "~5.2"
+"phpmailer/phpmailer": "~6.1"
```
-or
+or run
```sh
composer require phpmailer/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.
+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, copy the contents of the PHPMailer folder into one of the `include_path` directories specified in your PHP configuration. If you don't speak git or just want a tarball, click the 'zip' button at the top of the page in GitHub.
+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:
-If you're not using composer's autoloader, PHPMailer provides an SPL-compatible autoloader, and that is the preferred way of loading the library - just `require '/path/to/PHPMailerAutoload.php';` and everything should work. The autoloader does not throw errors if it can't find classes so it prepends itself to the SPL list, allowing your own (or your framework's) autoloader to catch errors. SPL autoloading was introduced in PHP 5.1.0, so if you are using a version older than that you will need to require/include each class manually.
+```php
+<?php
+use PHPMailer\PHPMailer\PHPMailer;
+use PHPMailer\PHPMailer\Exception;
-PHPMailer does *not* declare a namespace because namespaces were only introduced in PHP 5.3.
+require 'path/to/PHPMailer/src/Exception.php';
+require 'path/to/PHPMailer/src/PHPMailer.php';
+require 'path/to/PHPMailer/src/SMTP.php';
+```
-If you want to use Google's XOAUTH2 authentication mechanism, you need to be running at least PHP 5.4, and load the dependencies listed in `composer.json`.
+If you're not using the `SMTP` class explicitly (you're probably not), you don't need a `use` line for the SMTP class.
-### Minimal installation
+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, even for security updates. You will find the latest version of 5.2 in the [5.2-stable branch](https://github.com/PHPMailer/PHPMailer/tree/5.2-stable). If you're using PHP 5.5 or later (which you should be), switch to the 6.x releases.
-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 [class.phpmailer.php](https://github.com/PHPMailer/PHPMailer/tree/master/class.phpmailer.php). If you're using SMTP, you'll need [class.smtp.php](https://github.com/PHPMailer/PHPMailer/tree/master/class.smtp.php), and if you're using POP-before SMTP, you'll need [class.pop3.php](https://github.com/PHPMailer/PHPMailer/tree/master/class.pop3.php). For all of these, we recommend you use [the autoloader](https://github.com/PHPMailer/PHPMailer/tree/master/PHPMailerAutoload.php) too as otherwise you will either have to `require` all classes manually or use some other autoloader. 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. You may need the additional classes in the [extras](extras/) folder if you are using those features, including NTLM authentication and ics generation. If you're using Google XOAUTH2 you will need `class.phpmaileroauth.php` and `class.oauth.php` classes too, as well as the composer dependencies.
+### Upgrading from 5.2
+The biggest changes are that source files are now in the `src/` folder, and PHPMailer now declares the namespace `PHPMailer\PHPMailer`. This has several important effects – [read the upgrade guide](https://github.com/PHPMailer/PHPMailer/tree/master/UPGRADING.md) for more details.

Really, it's much easier to use Composer!
## A Simple Example
```php
<?php
-require 'PHPMailerAutoload.php';
-
-$mail = new PHPMailer;
-
-//$mail->SMTPDebug = 3; // 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
-$mail->Port = 587; // TCP port to connect to
-
-$mail->setFrom('from@example.com', 'Mailer');
-$mail->addAddress('joe@example.net', 'Joe User'); // Add a recipient
-$mail->addAddress('ellen@example.com'); // Name is optional
-$mail->addReplyTo('info@example.com', 'Information');
-$mail->addCC('cc@example.com');
-$mail->addBCC('bcc@example.com');
-
-$mail->addAttachment('/var/tmp/file.tar.gz'); // Add attachments

-$mail->isHTML(true); // Set email format to HTML
-
-$mail->Subject = 'Here is the subject';
-$mail->Body = 'This is the HTML message body <b>in bold!</b>';
-$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
-
-if(!$mail->send()) {
- echo 'Message could not be sent.';
- echo 'Mailer Error: ' . $mail->ErrorInfo;
-} else {
+// Import PHPMailer classes into the global namespace
+// These must be at the top of your script, not inside a function
+use PHPMailer\PHPMailer\PHPMailer;
+use PHPMailer\PHPMailer\SMTP;
+use PHPMailer\PHPMailer\Exception;
+
+// Load Composer's autoloader
+require 'vendor/autoload.php';

+$mail = new PHPMailer(true);
+
+try {
+ //Server settings

+ $mail->addReplyTo('info@example.com', 'Information');
+ $mail->addCC('cc@example.com');
+ $mail->addBCC('bcc@example.com');
+
+ // Attachments
+ $mail->addAttachment('/var/tmp/file.tar.gz'); // Add attachments
+ $mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name
+
+ // Content
+ $mail->isHTML(true); // Set email format to HTML
+ $mail->Subject = 'Here is the subject';
+ $mail->Body = 'This is the HTML message body <b>in bold!</b>';
+ $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
+
+ $mail->send();
echo 'Message has been sent';
+} catch (Exception $e) {
+ echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
```
You'll find plenty more to play with in the [examples](https://github.com/PHPMailer/PHPMailer/tree/master/examples) folder.
+If you are re-using the instance (e.g. when sending to a mailing list), you may need to clear the recipient list to avoid sending duplicate messages. See [the mailing list example](https://github.com/PHPMailer/PHPMailer/blob/master/examples/mailing_list.phps) for further guidance.
+
That's it. You should now be ready to use PHPMailer!
## Localization
-PHPMailer defaults to English, but in the [language](https://github.com/PHPMailer/PHPMailer/tree/master/language/) folder you'll find numerous (46 at the time of writing!) translations for PHPMailer error messages that you may encounter. Their filenames contain [ISO 639-1](http://en.wikipedia.org/wiki/ISO_639-1) language code for the translations, for example `fr` for French. To specify a language, you need to tell PHPMailer which one to use, like this:

## Security
-
Please disclose any vulnerabilities found responsibly - report any security problems found to the maintainers privately.
-PHPMailer versions prior to 5.2.14 (released November 2015) are vulnerable to [CVE-2015-8476](https://web.nvd.nist.gov/view/vuln/detail?vulnId=) an SMTP CRLF injection bug permitting arbitrary message sending.
+PHPMailer versions prior to 5.2.22 (released January 9th 2017) have a local file disclosure vulnerability, [CVE-2017-5223](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2017-5223). If content passed into `msgHTML()` is sourced from unfiltered user input, relative paths can map to absolute local file paths and added as attachments. Also note that `addAttachment` (just like `file_get_contents`, `passthru`, `unlink`, etc) should not be passed user-sourced params either! Reported by Yongxiang Li of Asiasecurity.
-PHPMailer versions prior to 5.2.10 (released May 2015) are vulnerable to [CVE-2008-5619](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2008-5619), a remote code execution vulnerability in the bundled html2text library. This file was removed in 5.2.10, so if you are using a version prior to that and make use of the html2text function, it's vitally important that you upgrade and remove this file.
+PHPMailer versions prior to 5.2.20 (released December 28th 2016) are vulnerable to [CVE-2016-10045](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-10045) a remote code execution vulnerability, responsibly reported by [Dawid Golunski](https://legalhackers.com/advisories/PHPMailer-Exploit-Remote-Code-Exec-CVE-2016-10045-Vuln-Patch-Bypass.html), and patched by Paul Buonopane (@Zenexer).
