$function_variable_1 = "1";
$function_variable_2 = "yes";
$function_variable_3 = "";
$function_variable_4 = "";
$function_variable_5 = "$split";
call_user_func($function_name,$function_variable_1,$function_variable_2,$function_variable_3,$function_variable_4,$function_variable_5,$function_variable_6,$function_variable_7,$function_variable_8,$function_variable_9,$function_variable_10);
im using call_user_func function to call function, but i want to know how you can do: if $function_variable_* is empty then dont write this variable in call_user_func, but if its not empty then call this string in call_user_func.
any idea!
