Your solution seems fine to me. You just save a couple of lines with  
array_splice.

I think you want array_splice, not array_slice.

array_splice removes a section of an array an optionally replaces it  
with another array. It resets the keys of the array if it is  
numerically indexed. In your case, you leave out the replacement  
argument.

An example in your context might look like this:

array_splice($_SESSION['sessiondisplay'], $_SESSION 
['sessionviewpointer'], 1);

This would only makes sense if $_SESSION['sessiondisplay'] is a  
numerically indexed array, and if $_SESSION['sessionviewpointer'] is  
an int.
