Fetching mail from a POP3 server with Zend_Mail

I was in a need for a class to get mails from a pop server to process them, so I’ve decided to leverage the Zend_Mail class, what I did was to create a wrapper around the Zend_Mail, to return all the messages from the server in a manageable way.

The first step was to put the needed Zend files in my library folder:

lib/Zend/Mail.php
Mail
|-- Exception.php
|-- Message
|   |-- File.php
|   `-- Interface.php
|-- Message.php
|-- Part
|   |-- File.php
|   `-- Interface.php
|-- Part.php
|-- Protocol
|   |-- Abstract.php
|   |-- Exception.php
|   |-- Imap.php
|   |-- Pop3.php
|   |-- Smtp
|   |   `-- Auth
|   |       |-- Crammd5.php
|   |       |-- Login.php
|   |       `-- Plain.php
|   `-- Smtp.php
|-- Storage
|   |-- Abstract.php
|   |-- Exception.php
|   |-- Folder
|   |   |-- Interface.php
|   |   |-- Maildir.php
|   |   `-- Mbox.php
|   |-- Folder.php
|   |-- Imap.php
|   |-- Maildir.php
|   |-- Mbox.php
|   |-- Pop3.php
|   `-- Writable
|       |-- Interface.php
|       `-- Maildir.php
|-- Storage.php
`-- Transport
    |-- Abstract.php
    |-- Exception.php
    |-- Sendmail.php
    `-- Smtp.php

Then I started writing my class:

< ?php
 
set_include_path('lib' . PATH_SEPARATOR . get_include_path());
 
include_once 'Zend/Mail.php';
include_once 'Zend/Mail/Storage/Pop3.php';
include_once 'Zend/Mail/Transport/Smtp.php';
include_once 'Zend/Mime/Part.php';
 
/**
 * Class to get mails from a server
 */
class mailFetcher
{
    private $_emailHost = 'pop.server.com';
    private $_emailUser = 'ivan@ivanvillareal.com';
    private $_emailPass = 'password';
	/**
	 * Zend_Mail_Storage
	 */
    private $_mail;
	/**
	 * Inbox wrapper
	 */
	private $_inbox = array();
 
	/**
	 * on class instantiation we fire connect
	 * to the pop server and start fetching the mails
	 */
    public function __construct()
    {
        try {
            $this->_mail = new Zend_Mail_Storage_Pop3(array(
                                             'host' => $this->_emailHost,
                                             'user' => $this->_emailUser,
                                             'password' => $this->_emailPass));
        } catch (Exception $e) {
            echo 'Mail Retrieval Failed...' . PHP_EOL;
            die();
        }      
        $this->processMail();
    }
 
 
	private function _contentDecoder($encoding, $content)
	{
		switch ($encoding) {
			case 'quoted-printable':
				$result = quoted_printable_decode($content);
			break;
			case 'base64':
				$result = base64_decode($content);
			break;
			default:
				$result = $content;
			break;
		}
		return $result;
	}
 
	/**
	 * This is where everything is done
	 */
	public function processMail()
	{
		if ($this->_mail instanceof Zend_Mail_Storage_Pop3 && $this->_mail->countMessages() > 0) {
			$messageNum = 0;
			foreach ($this->_mail as $message) {
				$messageNum++;
				$rawMail      = $this->_mail->getRawHeader($messageNum) . $this->_mail->getRawContent($messageNum);
				$received     = $message->received;
				$date         = date('Y-m-d H:i:s', strtotime($message->date));
				$messageId    = $message->headerExists('message-id') ? $message->getHeader('message-id') : null;
				//remove <> from message id
				$messageId    = (preg_match('|< (.*?)>|', $messageId, $regs)) ? $regs[1] : $messageId;
				$inReplyTo    = $message->headerExists('in-reply-to') ? $message->getHeader('in-reply-to') : null;
				//remove <> from in-reply-to
				$inReplyTo    = (preg_match('|< (.*?)>|', $inReplyTo, $regs)) ? $regs[1] : $inReplyTo;
				$references   = $message->headerExists('References')  ? $message->getHeader('References') : null;
				//remove <> from references
				$references   = (preg_match('|< (.*?)>|', $references, $regs)) ? $regs[1] : $references;
				$from         = $message->from;
				$subject      = $message->subject;
				$to           = $message->to;
				$plainContent = null;
				$htmlContent  = null;
				$attachments = array();
 
				/**
				 * Check if the message has multiple parts
				 */
		        if ($message->isMultipart()) {
					/**
					 * We have a multipart message
					 * lets extract the plain content,
					 * html content, and attachments
					 */
					foreach (new RecursiveIteratorIterator($message) as $part) {
						try {
							switch (strtok($part->contentType, ';')) {
								case 'text/plain':
									$plainContent = $this->_contentDecoder($part->getHeader('content-transfer-encoding'), $part->getContent());
								break;
								case 'text/html':
									$htmlContent = $this->_contentDecoder($part->getHeader('content-transfer-encoding'), $part->getContent());
								break;
								default: //attachment handle
									$type       = strtok($part->contentType, ';');
									$fileName   = $part->getHeader('content-description');
									$attachment = $this->_contentDecoder($part->getHeader('content-transfer-encoding'), $part->getContent());
									$attachments[] = array(
													   'file_name' => $fileName,
													   'type'      => $type,
													   'content'	=> $attachment);
								break;
							}
						} catch (Zend_Mail_Exception $e) {
							echo "$e \n";
						}
					}
				} else {
					$plainContent = $message->getContent();
				}
				$this->_inbox[] = array('messageNumber' => $messageNum,
									    'rawMail'       => $rawMail,
										'received'		=> $received,
										'date'			=> $date,
										'messageId'		=> $messageId,
										'inReplyTo'		=> $inReplyTo,
										'references'	=> $references,
										'from'			=> $from,
										'subject'		=> $subject,
										'to'			=> $to,
										'plainContent'	=> $plainContent,
										'htmlContent'	=> $htmlContent,
										'attachments'	=> $attachments);
			}
		} else {
			$this->_inbox = false;
		}
	}
	public function getInbox()
	{
		return $this->_inbox;
	}
}

My fetch class does everything on instantiation, and it will have all the mails retreived, so for example if I need to get all messages I can do this:

< ?php
include_once 'mailFetcher.php';
 
$inbox = new mailFetcher();
print_r($inbox->getInbox());

And this would be the result:

    [0] => Array

From this point I can iterate the inbox easily saving the email results or applying other logic to it,
