PHP IMAP library

Latest Stable Version Downloads Integrate Code Coverage

A PHP IMAP library to read and process e-mails over IMAP protocol, built with robust Object-Oriented architecture.

This library requires PHP >= 7.4 with IMAP, iconv and Multibyte String extensions installed.

Installation

The recommended way to install the IMAP library is through Composer:

$ composer require ddeboer/imap

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.

Usage

Connect and Authenticate

use Ddeboer\Imap\Server;

$server = new Server('imap.gmail.com');

// $connection is instance of \Ddeboer\Imap\Connection $connection = $server->authenticate('my_username', 'my_password');

You can specify port, flags and parameters to the server:

$server = new Server(
    $hostname, // required
    $port,     // defaults to '993'
    $flags,    // defaults to '/imap/ssl/validate-cert'
    $parameters
);

Mailboxes

Retrieve mailboxes (also known as mail folders) from the mail server and iterate over them:

$mailboxes = $connection->getMailboxes();

foreach ($mailboxes as $mailbox) { // Skip container-only mailboxes // @see https://secure.php.net/manual/en/function.imap-getmailboxes.php if ($mailbox->getAttributes() & \LATT_NOSELECT) { continue; }

// $mailbox is instance of \Ddeboer\Imap\Mailbox
printf('Mailbox "%s" has %s messages', $mailbox->getName(), $mailbox->count());

}

Or retrieve a specific mailbox:

$mailbox = $connection->getMailbox('INBOX');

Delete a mailbox:

$connection->deleteMailbox($mailbox);

You can bulk set, or clear, any flag of mailbox messages (by UIDs):

$mailbox->setFlag('\\Seen \\Flagged', ['1:5', '7', '9']);
$mailbox->setFlag('\\Seen', '1,3,5,6:8');

$mailbox->clearFlag('\Flagged', '1,3');

WARNING You must retrieve new Message instances in case of bulk modify flags to refresh the single Messages flags.

Messages

Retrieve messages (e-mails) from a mailbox and iterate over them:

$messages = $mailbox->getMessages();

foreach ($messages as $message) { // $message is instance of \Ddeboer\Imap\Message }

To insert a new message (that just has been sent) into the Sent mailbox and flag it as seen:

$mailbox = $connection->getMailbox('Sent');
$mailbox->addMessage($messageMIME, '\\Seen');

Note that the message should be a string at MIME format (as described in the RFC2045).

Searching for Messages

use Ddeboer\Imap\SearchExpression;
use Ddeboer\Imap\Search\Email\To;
use Ddeboer\Imap\Search\Text\Body;

$search = new SearchExpression(); $search->addCondition(new To('[email protected]')); $search->addCondition(new Body('contents'));

$messages = $mailbox->getMessages($search);

WARNING We are currently unable to have both spaces and double-quotes escaped together. Only spaces are currently escaped correctly. You can use

Ddeboer\Imap\Search\RawExpression
to write the complete search condition by yourself.

Messages can also be retrieved sorted as per imap_sort function:

$today = new DateTimeImmutable();
$thirtyDaysAgo = $today->sub(new DateInterval('P30D'));

$messages = $mailbox->getMessages( new Ddeboer\Imap\Search\Date\Since($thirtyDaysAgo), \SORTDATE, // Sort criteria true // Descending order );

Unknown search criterion: OR

Note that PHP imap library relies on the

c-client
library available at https://www.washington.edu/imap/ which doesn't fully support some IMAP4 search criteria like
OR
. If you want those unsupported criteria, you need to manually patch the latest version (
imap-2007f
of 23-Jul-2011 at the time of this commit) and recompile PHP onto your patched
c-client
library.

By the way most of the common search criteria are available and functioning, browse them in

./src/Search
.

Message Properties and Operations

Get message number and unique message id in the form <...>:

$message->getNumber();
$message->getId();

Get other message properties:

$message->getSubject();
$message->getFrom();    // Message\EmailAddress
$message->getTo();      // array of Message\EmailAddress
$message->getDate();    // DateTimeImmutable
$message->isAnswered();
$message->isDeleted();
$message->isDraft();
$message->isSeen();

Get message headers as a \Ddeboer\Imap\Message\Headers object:

$message->getHeaders();

Get message body as HTML or plain text:

$message->getBodyHtml();    // Content of text/html part, if present
$message->getBodyText();    // Content of text/plain part, if present

Reading the message body keeps the message as unseen. If you want to mark the message as seen:

$message->markAsSeen();

Or you can set, or clear, any flag:

$message->setFlag('\\Seen \\Flagged');
$message->clearFlag('\\Flagged');

Move a message to another mailbox:

$mailbox = $connection->getMailbox('another-mailbox');
$message->move($mailbox);

Deleting messages:

$mailbox->getMessage(1)->delete();
$mailbox->getMessage(2)->delete();
$connection->expunge();

Message Attachments

Get message attachments (both inline and attached) and iterate over them:

$attachments = $message->getAttachments();

foreach ($attachments as $attachment) { // $attachment is instance of \Ddeboer\Imap\Message\Attachment }

Download a message attachment to a local file:

// getDecodedContent() decodes the attachment’s contents automatically:
file_put_contents(
    '/my/local/dir/' . $attachment->getFilename(),
    $attachment->getDecodedContent()
);

Embedded Messages

Check if attachment is embedded message and get it:

$attachments = $message->getAttachments();

foreach ($attachments as $attachment) { if ($attachment->isEmbeddedMessage()) { $embeddedMessage = $attachment->getEmbeddedMessage(); // $embeddedMessage is instance of \Ddeboer\Imap\Message\EmbeddedMessage } }

An EmbeddedMessage has the same API as a normal Message, apart from flags and operations like copy, move or delete.

Timeouts

The IMAP extension provides the imap_timeout function to adjust the timeout seconds for various operations.

However the extension's implementation doesn't link the functionality to a specific context or connection, instead they are global. So in order to not affect functionalities outside this library, we had to choose whether wrap every

imap_*
call around an optional user-provided timeout or leave this task to the user.

Because of the heterogeneous world of IMAP servers and the high complexity burden cost for such a little gain of the former, we chose the latter.

Mock the library

Mockability is granted by interfaces present for each API. Dig into MockabilityTest for an example of a mocked workflow.

Running the Tests

This library is functionally tested on Travis CI against a local Dovecot server.

If you have your own IMAP (test) account, you can run the tests locally by providing your IMAP credentials:

$ composer install
$ IMAP_SERVER_NAME="my.imap.server.com" IMAP_SERVER_PORT="60993" IMAP_USERNAME="johndoe" IMAP_PASSWORD="p4ssword" vendor/bin/phpunit

You can also copy

phpunit.xml.dist
file to a custom
phpunit.xml
and put these environment variables in it.

WARNING Tests create new mailboxes without removing them.

$ docker-compose run tests
