Friendster switched to PHP from their previous Java solution and became much faster. You can debate the cause of it (which lots of people are doing), but I'd recommend checking out Jeff Moore's large roundup of all related news and commentary. What seems to be coming out of this is that people are becoming aware of the merits of PHP's "shared nothing" architecture.
Update: George has a cranky, snarky answer to why PHP scales that should be very much worth your time to read. You may also want to check out The J2EE guy still doesn't get PHP, by Harry Fuecks.
Update: More from Sterling and John.
Update: Jeff Moore rounds up some more commentary and asks, "Scalability - YAGNI?"
Update: More summary here.
