PHP IMAP Email script - to receive and send emails via imap details

General information for the website: Email PHP IMAP
Description of requirements/features: I am looking for a PHP developer experienced with PHP IMAP.

I would like you to write 2 php functions that will fetch and send emails from an IMAP or POP3 email account, based on the server details entered.

Ideally it will simply be a stand alone script containing the two functions, something like this:

function getemails($imapdetails){
php code here;
$emails = array containing all emails and details;
return $emails;
}

function sendemail($imapdetails,$email){
php code here;
$success = yes or no to let me know whether email was sent successfully;
return $success;
}

Although of course if there is a simpler option, that's fine.

Clarification:

The scripts DO NOT need to update the IMAP server in any way
Emails do not need to be marked as read
Sent emails do not need to be added to the IMAP server
getemails function only needs to poll the inbox (no folders)
All I need is an array containing all of the emails in the inbox

Attachments:

I would like any attachments to be given a random name and uploaded to my server (the same server as where the PHP script will be hosted), the name of the file should then be returned in the array.

Thanks for your bid, any questions are welcome.
