IMAP functionality in CodeIgniter
The point of this article is to develop some kind of IMAP functionality to CI, to connect to a mail server through IMAP, POP3 or NNTP.
Also to make a Class with the most used functions in building a webmail service.
EDIT… (by sophistry) A full wrapper class can be found at this page:
http://codeigniter.com/wiki/imap_pop_class/
<?php
/* Controller: Mail */
class Mail extends Controller {
// IMAP/POP3 (mail server) LOGIN
var $imap_server = 'mail.example.org';
var $imap_user = 'user@example.org';
var $imap_pass = 'password';
// Constuctor
function __construct() {
parent::Controller();
$this->load->library('Imap');
}
// index
function index() {
$inbox = $this->imap->cimap_open($this->imap_server, 'INBOX', $this->imap_user, $this->imap_pass) or die(imap_last_error());
$data_array['totalmsg'] = $this->imap->cimap_num_msg($inbox);
$data_array['quota'] = $this->imap->cimap_get_quota($inbox);
$this->load->view('mail_view', $data_array);
}
}
?>
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
/* Library Class: Imap */
class Imap {
// Open IMAP connection
function cimap_open($host, $mailbox, $username, $password)
{
return imap_open('{'.$host.':143}'.$mailbox, $username, $password);
}
// Find number of msg in mailbox
function cimap_num_msg($imap_connection)
{
return imap_num_msg($imap_connection);
}
// Find disk quota amount
function cimap_get_quota($imap_connection)
{
$storage = $quota['STORAGE']= imap_get_quotaroot($imap_connection, "INBOX");
function kilobyte($filesize)
{
return round($filesize / 1024, 2) . ' Mb';
}
return kilobyte($storage['usage']) . ' / ' . kilobyte($storage['limit']) . ' (' . round($storage['usage'] / $storage['limit'] * 100, 2) . '%)';
}
}
?>
/* mail_view */
Will return something like:
Total messages: 13
Quota: 8.27 Mb / 10 Mb (82.67%)
