Sara Golemon shares an interesting bit of stats in her latest post - the release dates from the major PHP version releases since PHP 4.0.0.

Someone recently posed the question: "How can I find out when a particular version of PHP was released?" I pointed him to CVS main/php_version.h, then went about taking my own medicine. Here's what I got from a quick scan of the cvs log for that oft-touched file in case anyone else gets curious...

The list (of 48 items) shows a few fun things she points out - PHP's 7th birthday is coming up next month (May 2007), the file was usually tagged before the actual release date, and version 4.0.4's info points to an invalid file so its date is a guess at best.
