If I defined a function with 4 parameters but only pass 3 I get an
error. Is there anyway around this?
 
I want to be able to set the missing parameter to a default value if it
is not passed which works ok but How do I get rid of the error message?

http://us2.php.net/manual/en/function.func-num-args.php "func_num_args()
may be used in conjunction with func_get_arg() and func_get_args() to
allow user-defined functions to accept variable-length argument lists. "
