Via php|architect today, there's a pointer to the latest PHP statistics over on Nexen.net.

Here are the statistics for the popularity of PHP for September 2005. To check out a certain domain, you can see here. There were 9.5 million servers tested in June and 5.5 million were kept for the statistics - some didn't have websites on them, some were inaccessbile, some were just parked domains - these stats were removed from the list.
