Trying to install the bot running with php5 exe's and dll's.

I get following after running the "php start.php":

Fatal error: Only variables can be passed by reference in C:\bebot\AOChat.php on line 854

AOChat.php that I use looks like this

Any ideas what I've missed / done wrong. Tried to follow the guides, and my php.ini looks like:

extension_dir = ./

extension=php_bz2.dll
extension=php_mysql.dll
extension=php_sockets.dll
