One that I've seen bits of that I like, though I don't have it in paper, is the O'Reilly PHP book authored by Rasmus Lehrdorf. That guy really knows a thing or two about PHP. And he's not bad at explaining things either.
royalelephant, you can find information regarding "paper versions" in the Library reference I showed earlier, particularly the thread on Learning PHP - Books, Tutorials and Online Resources [webmasterworld.com].
