The library passes reply messages from email to predefined objects. It uses IMAP to connect email servers.

The library uses ddeboer/imap and it requires:

• PHP >= 7.1
• extensions iconv, IMAP, mbstring

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist tigrov/email-reply

or add

"tigrov/email-reply": "~1.0"

to the require section of your composer.json file.

First of all you need to configure your email server. Create special mailbox and redirect all the mails sent to non-existent mailboxes. The server must accepts IMAP connections.

Then you can take steps:

1. Create a model class with ModelInterface interface and implement the necessary methods (see examples/Model.php).

   class Model implements ModelInterface
   {
       public static function paramNames() {}
   
       public function paramValues() {}
   
       public static function buildFromParams($paramValues) {}
   
       public function emailReply($message) {}
   }

2. Create and configure EmailReply object.

   $config = [
       'classesMap' => [
           // key will be used as prefix for email address
           'model' => \Model::class,
           // email for reply will be like [email protected]
           // or
           // 'm' => \Model::class,
           // email for reply will be like [email protected]
           // where 5 is id of a model
       ],
   ];
   
   $emailReply = new EmailReply($config);

3. Send a email message with a special reply email address.

   $email = $emailReply->getReplyEmail($model, 'domain.com');
   
   // Send an email to somebody with the reply email $email
   // ...

4. Read your mailboxes using IMAP. For example as cron job.

   $server = new Server($host, $port);
   
   $connection = $server->authenticate($username, $password);
   
   $mailboxModels = Reader::getMailboxModels($connection);
   
   $messages = Reader::getIterator($mailboxModels);
   
   $emailReply->read($messages);
   
   $connection->expunge();

5. Each message will be passed to ModelInterface::emailReply($message) where you can precess them.

   class Model implements ModelInterface
   {
       // ...
   
       public function emailReply($message)
       {
           /** @var string $fromEmail email address of the sender */
           $fromEmail = $message->getFrom()->getAddress();
           
           /** @var string $fromName name of the sender */
           $fromName = $message->getFrom()->getName();
           
           /** @var string $content content from the replied message */
           $content = $message->getBodyHtml() ?: $message->getBodyText() ?: $message->getDecodedContent();
           
           // Parse the content to get only answer
           $content = EmailReplyParser::parseReply($content);
           
           // To do something with $content
           // e.g. add comment from $fromEmail to the object 
       }

See examples directory for examples.

Also see EmailReply for Yii2.

You can use willdurand/email-reply-parser to parse only reply text from email messages.

$reply = EmailReplyParser::parseReply($content);
