Forget "Spot The Difference". How about "Spot The Correct Bit". Surely that's more difficult to identify.And what's an "associate array" anyway? And why do some authors think they can get away with just making syntax up?Judging by the font, this looks like an Oracle Press book. This kind of technical blunder is an example of what happens when technical editors a) know less than the author; b) are non-existent; or c) gave up after three chapters of correcting this stuff.
