note 4391 modified in imap_open by ronabop

The use of variables with imap_open as the mailbox works with PHP3. So this is valid with PHP3: imap_open("{$server:$port}$mailbox", $user, $pass); but with PHP4 this doesn't work anymore, i think it is the two chars "{$" that gives confusion to PHP4 so you must use it this way: imap_open("{" . $server . "}" . $mailbox, $user, $pass); An other alternative would be to define the a mailbox variable before and add it to the imap_open function. Regards http://www.php.net/manual/function.imap-open.php
