Is there a function to c if a php function exists

I have been implementing a system on a different ISP than I normally use and have got:- Fatal error: Call to undefined function: cal_days_in_month() in /home/hosted/www.menublackboard.com/public_html/dev/classes/validator.class.php on line 134 I found a reference to this an the web and it seems PHP is not compiled with calender support. "recompile php with the "--enable-calendar" option." Cant see being able to get the to re-compile PHP so I guess I am going to have to disable the feature. I seem to remember a while ago seeing a function to test weather a function exists in PHP. That way I can have the relevant validation skipped if the function is missing (I will tell the client if they get decent hosting it will start working). So something like function_exists( cal_days_in_month() ) Anyone know what the function is called.
