In the display_list() function, you actually begin to use PHP’s IMAP functions.The
two key parts of this function are opening the mailbox and reading the message headers.
You open the mailbox for a user account with a call to the open_mailbox() function
written in mail_fns.php.This function is shown in Listing 29.9.
Listing 29.9 open_mailbox() Function from mail_fns.php—This Function
Connects to a User Mailbox
function open_mailbox($auth_user, $accountid) {
// select mailbox if there is only one
if(number_of_accounts($auth_user)==1) {
$accounts = get_account_list($auth_user);
$_SESSION['selected_account'] = $accounts[0];
$accountid = $accounts[0];
}
// connect to the POP3 or IMAP server the user has selected
$settings = get_account_settings($auth_user, $accountid);
if(!sizeof($settings)) {
return 0;
}
$mailbox = '{'.$settings[server];
if($settings[type]=='POP3') {
$mailbox .= '/pop3';
}
$mailbox .= ':'.$settings[port].'}INBOX';
// suppress warning, remember to check return value
@$imap = imap_open($mailbox, $settings['remoteuser'],
$settings['remotepassword']);
return $imap;
}
You actually open the mailbox with the imap_open() function, which has the following
prototype:
int imap_open (string mailbox, string username, string password [, int options])
