Damien Seguy has posted this month's PHP statistics (for the month of October 2007). Here's some of the highlights:

• PHP 5 reaches a quarter of the PHP market
• PHP 4.4.7 is the last standing
• The elePHPant as no impact on the stats

You can find the full stats (including all the graphs you could want) here (evolution stats) and here (for the version statistics). Also, if you have no idea what the elePHPant is about, check out this post for the details and this post to find out how to get your own.
