I have 2 multidimensional arrays which i have to print simultaneously and one of them will not have same number of elements at some times. So i check them using empty() function. As it is not possible to check every single element, i wrote a function which has to check the elements index (i pass these as arguments)and do the remaining process. But here the problem is that the function is not passing if the element is empty and this effects the other array to be printed properly.
I would be thankful if some one could tell me how to pass empty/NULL values to functions or how to make function accept the empty/NULL values to pass as arguments.
