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, Zend/Mail, eZcomponents etc.
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
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
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 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.
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, 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.
The 5.2 branch will not receive security updates after December 31st 2018.
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 for more details.
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. If you're using SMTP, you'll need src/SMTP.php, and if you're using POP-before SMTP, you'll need src/POP3.php. You can skip the 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 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
You'll find plenty more to play with in the examples folder.
That's it. You should now be ready to use PHPMailer!
PHPMailer defaults to English, but in the language folder you'll find numerous (48 at the time of writing!) translations for PHPMailer error messages that you may encounter. Their filenames contain 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:
We welcome corrections and new languages - if you're looking for corrections to do, run the PHPMailerLangTest.php script in the tests folder and it will show any missing translations.
Start reading at the GitHub wiki. If you're having trouble, this should be the first place you look as it's the most frequently updated.
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, so you'll need to either clone the git repository or use the above links to get to the examples directly.
Complete generated API documentation is available online.
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 installed. You may find the unit tests a good source of how to do various operations such as encryption.
If the documentation doesn't cover what you need, search the many questions on Stack Overflow, and before you ask a question about "SMTP Error: Could not connect to SMTP host.", read the troubleshooting guide.
There is a PHPUnit test script in the test folder. PHPMailer uses PHPUnit 4.8 - we would use 5.x but we need to run on PHP 5.5.
If this isn't passing, is there something you can do to help?
Please disclose any vulnerabilities found responsibly - report any security problems found to the maintainers privately.
PHPMailer versions prior to 5.2.22 (released January 9th 2017) have a local file disclosure vulnerability, 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
unlink, etc) should not be passed user-sourced params either! Reported by Yongxiang Li of Asiasecurity.
PHPMailer versions prior to 5.2.20 (released December 28th 2016) are vulnerable to CVE-2016-10045 a remote code execution vulnerability, responsibly reported by Dawid Golunski, and patched by Paul Buonopane (@Zenexer).
See SECURITY for more detail on security issues.
Please submit bug reports, suggestions and pull requests to the GitHub issue tracker.
We're particularly interested in fixing edge-cases, expanding test coverage and updating translations.
If you found a mistake in the docs, or want to add something, go ahead and amend the wiki - anyone can edit it.
If you have git clones from prior to the move to the PHPMailer GitHub organisation, you'll need to update any remote URLs referencing the old GitHub location with a command like this from within your clone:
Please don't use the SourceForge or Google Code projects any more; they are obsolete and no longer maintained.

- Test suite.
- Continuous integration with Travis-CI.
- Composer support.
- Public development.
- Additional languages and language strings.
- CRAM-MD5 authentication support.
- Preserves full repo history of authors, commits and branches from the original SourceForge project.
