Are << and >> signed or not? E.g.
is 1100 >> 1 = 1110 or 0110?

I am using PHP5, if I want unsigned binary shift, do i have any
options other than converting to  a string using base_convert and
writing my own function to shift the bits and then convert back to a
number?

Is what i am after planned if not availible already?

You could use BC: bcdiv($a, 2); to do $a >> 1;
