Counting Neighboring Cells

Hi, I've been recently having trouble in creating a functions that would count the number of neighboring 1's in an array. So say for example I had an array that consisted of

1 0 1 1 0 1 1 0

1 1 0 1 0 1 1 0

I would want it to return

2 4 3 2 4 3 3 2

2 3 4 2 4 3 3 2

How would I go about this?

Much appreciated

A=[1 0 1 1 0 1 1 0;
   1 1 0 1 0 1 1 0]

B = ones(3);
B(2,2) = 0;
conv2(A,B,'same')
