Damien Seguy just sent me more stats on the versions of PHP in the wild. From their analysis of PHP Statistics for November 2007:
- PHP 5 still vigourous, up to 26%
- PHP 4.4.7 is the last growing PHP 4 version
- PHP 5.2 will take over PHP 4.3 in the next months
With support for PHP 4 ending in a couple of weeks, hopefully the 50% or so of PHP installations running PHP 4 or earlier will take the opportunity to migrate. (See the PHP 4 to PHP 5 migration guide.)
In a related note, I really like the plush PHP elePHPant.
