28 ## Why you might need it
29 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.
31 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!
32 *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/), [ZetaComponents](https://github.com/zetacomponents/Mail) etc.
34 The PHP `mail()` function usually sends via a local mail server, typically fronted by a `sendmail` binary on Linux, BSD, and macOS 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.

39 ## Installation & loading
40 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:
43 "phpmailer/phpmailer": "~6.1"
49 composer require phpmailer/phpmailer
52 Note that the `vendor` folder and the `vendor/autoload.php` script are generated by Composer; they are not part of PHPMailer.
54 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`.
56 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:
60 use PHPMailer\PHPMailer\PHPMailer;
61 use PHPMailer\PHPMailer\Exception;
63 require 'path/to/PHPMailer/src/Exception.php';
64 require 'path/to/PHPMailer/src/PHPMailer.php';
65 require 'path/to/PHPMailer/src/SMTP.php';
68 If you're not using the `SMTP` class explicitly (you're probably not), you don't need a `use` line for the SMTP class.
70 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.
73 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.
75 ### Upgrading from 5.2
76 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.
78 ### Minimal installation
79 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!
85 // Import PHPMailer classes into the global namespace
86 // These must be at the top of your script, not inside a function
87 use PHPMailer\PHPMailer\PHPMailer;
88 use PHPMailer\PHPMailer\SMTP;
89 use PHPMailer\PHPMailer\Exception;
91 // Load Composer's autoloader
92 require 'vendor/autoload.php';
94 // Instantiation and passing `true` enables exceptions
95 $mail = new PHPMailer(true);
99 $mail->SMTPDebug = SMTP::DEBUG_SERVER; // Enable verbose debug output
100 $mail->isSMTP(); // Send using SMTP
101 $mail->Host = 'smtp1.example.com'; // Set the SMTP server to send through
102 $mail->SMTPAuth = true; // Enable SMTP authentication
103 $mail->Username = 'user@example.com'; // SMTP username
104 $mail->Password = 'secret'; // SMTP password
105 $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; // Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` also accepted
106 $mail->Port = 587; // TCP port to connect to
109 $mail->setFrom('from@example.com', 'Mailer');
110 $mail->addAddress('joe@example.net', 'Joe User'); // Add a recipient
111 $mail->addAddress('ellen@example.com'); // Name is optional
112 $mail->addReplyTo('info@example.com', 'Information');
113 $mail->addCC('cc@example.com');
114 $mail->addBCC('bcc@example.com');
117 $mail->addAttachment('/var/tmp/file.tar.gz'); // Add attachments
118 $mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name
121 $mail->isHTML(true); // Set email format to HTML
122 $mail->Subject = 'Here is the subject';
123 $mail->Body = 'This is the HTML message body <b>in bold!</b>';
124 $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
127 echo 'Message has been sent';
128 } catch (Exception $e) {
129 echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
133 You'll find plenty more to play with in the [examples](https://github.com/PHPMailer/PHPMailer/tree/master/examples) folder.
135 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.
137 That's it. You should now be ready to use PHPMailer!
140 PHPMailer defaults to English, but in the [language](https://github.com/PHPMailer/PHPMailer/tree/master/language/) folder you'll find many 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:
143 // To load the French version
144 $mail->setLanguage('fr', '/optional/path/to/language/directory/');
147 We welcome corrections and new languages - if you're looking for corrections to do, run the [PHPMailerLangTest.php](https://github.com/PHPMailer/PHPMailer/tree/master/test/PHPMailerLangTest.php) script in the tests folder and it will show any missing translations.
150 Start reading at the [GitHub wiki](https://github.com/PHPMailer/PHPMailer/wiki). If you're having trouble, this should be the first place you look as it's the most frequently updated.
152 Examples of how to use PHPMailer for common scenarios can be found in the [examples](https://github.com/PHPMailer/PHPMailer/tree/master/examples) folder. If you're looking for a good starting point, we recommend you start with [the Gmail example](https://github.com/PHPMailer/PHPMailer/tree/master/examples/gmail.phps).
154 Note that in order to reduce PHPMailer's deployed code footprint, the examples are no longer included if you load PHPMailer via Composer or via [GitHub's zip file download](https://github.com/PHPMailer/PHPMailer/archive/master.zip), so you'll need to either clone the git repository or use the above links to get to the examples directly.
156 Complete generated API documentation is [available online](http://phpmailer.github.io/PHPMailer/).
158 You can generate complete API-level documentation by running `phpdoc` in the top-level folder, and documentation will appear in the `docs` folder, though you'll need to have [PHPDocumentor](http://www.phpdoc.org) installed. You may find [the unit tests](https://github.com/PHPMailer/PHPMailer/tree/master/test/phpmailerTest.php) a good source of how to do various operations such as encryption.
160 If the documentation doesn't cover what you need, search the [many questions on Stack Overflow](http://stackoverflow.com/questions/tagged/phpmailer), and before you ask a question about "SMTP Error: Could not connect to SMTP host.", [read the troubleshooting guide](https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting).
163 There is a PHPUnit test script in the [test](https://github.com/PHPMailer/PHPMailer/tree/master/test/) folder. PHPMailer uses PHPUnit 4.8 - we would use 5.x but we need to run on PHP 5.5.

167 If this isn't passing, is there something you can do to help?
170 Please disclose any vulnerabilities found responsibly - report any security problems found to the maintainers privately.
172 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.
174 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).
176 PHPMailer versions prior to 5.2.18 (released December 2016) are vulnerable to [CVE-2016-10033](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-10033) a critical remote code execution vulnerability, responsibly reported by [Dawid Golunski](http://legalhackers.com/advisories/PHPMailer-Exploit-Remote-Code-Exec-CVE-2016-10033-Vuln.html).
