Solution 2

I haven't programmed in php for a long, long time so I can only guess.
Try this :

PHP

$mailboxes=imap_list($this->connection,$this->serverName,'*');
if (is_array($mailboxes)) {
    foreach ($mailboxes as $val) {
        $mailbox=str_replace($this->serverName,'',$mailbox);
        echo "$mailbox";
    }
} else {
    echo "imap_list failed: " . imap_last_error() . "\n";
}

If you get an error, post it here (use Improve question)

My bad, it's $mailboxes

i have update code but it is not error, it return message "imap_list failed:".
is it a array?

Well, AFAIK if you got "imap_list failed:" without any additional detail about the error that means there's no mailboxes.
