Phillips, or Phillips head, refers to the shape of the screwdriver's tip. It forms an X or a cross at the tip, instead of being straight as in a flat head.
Phillips head screws and screwdrivers are less likely to slip while being turned, but it's more important to use the right size to avoid damaging the screw head.
Just the same as any other screw.

Phillips head screwdrivers only work on Phillips head screws--which are ones with an "x" indentation on the head of the screw. A straight screwdriver works on screws with a single line indentation on the head of the screw.
A Phillips screwdriver shaft is round with a pointed head with 4 tapering splines that engage the cross shaped indent in the screw head.
