The folks over at Nexen.net hve published this month's PHP adoption statistics for the month of September 2006:

Here are the evolution graphics for PHP, in September 2006. To learn about the methodology, see la section phpversion. 15 millions servers were surveyed during September 2006, and 8,9 were used for the stats : domaines without web sites, those unreachable, ISP or domain parkings were not considered.

According to this month's stats, there's a bit of a dip on PHP usage overall and a corresponding dip for the ASP side as well. The use of PHP4 has taken a nosedive with PHP5 coming up strong to fill the gap.

There's three main highlights from this month's stats:

• PHP5 users are hesitating, waiting for PHP 5.2
• PHP 4.4 is pushing even futher past the previous version (4.3)
• PHP 4.4.2 is still holding on strong as the most popular version in use
