myPHPChat

I need one chat for IRC servers written in PHP language and JavaScript of course) Anyone knows where I can find something like this ? Plz give me a good example not just places where to look about it... I also tried to use phpChat (from phpWizzard.net) but I have few errors and if someone use it plz help me... The errors are: "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 fsockopen(). 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 ../phpIRC/phpIRC.php on line 833" "Fatal error: Call to undefined function: shm_attach() in /home/sites/site7/users/jt/web/phpchat/chat_bot.php on line 927" I don't know why I get those errors because I didn't modify nothing at all in the scripts... just the config file...
