Warning: Call-time pass-by-reference has been deprecated

[mystcb]

In the file IMAP.INC on line 843, there is a call to a
function which is written as follows:

$num = iil_C_CountMessages(&$conn, $mailbox);

This produces the error:

Warning: Call-time pass-by-reference has been
deprecated - argument passed by value; If you would
like to pass it by reference, modify the declaration of
iil_c_countmessages(). If you would like to enable
call-time pass-by-reference, you can set
allow_call_time_pass_reference to true in your INI
file. However, future versions may not support this any
longer. in /home/www/roundcube/program/lib/imap.inc on
line 843

--

If you remove the & from the call to the function this
message goes away, so you replace the above line with:

$num = iil_C_CountMessages($conn, $mailbox);

This stops the messages from coming up, and does not
break the code. This will make the code compatible with
PHP5

Hope this helps
