Call-time pass-by-reference error

[cybergord]

In order to eliminate the problem of Call-time pass-by-reference errors
for some clients running very up to date php5 and where they dont have access to their php.ini to set allow_call_time_pass_reference to true. I have replaced the instance iof &$ with $ in a search and replace action throughout my open source php shopping cart software.

(this is a big problem on localhost WAMP and XAMPP also)

However I have found that it affects session creation and straight away Admin cannot login and user cannot login or add items to the shopping cart.

By replacing the files includes/classes/sessions.php with the originals

I can get it all to work ok......but what about the depreciated function variables &$ in the session files can this be rewritten for openfreeway.org? as to elininate call_time_pass_reference errors completely??

Can someone solve this problem for me or is it enough to leave the original session.php files in place without replacing the depreciated &$.

PHP 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 [runtime function name](). 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.
