Just to highlight some old PHP versions:
de3.php.net 4.3.1 May 16, 2003, 10:12 pm Alex Kiesel <kiesel@schlund.de>
it.php.net 4.3.1 May 16, 2003, 10:12 pm fmal@fmal.com
Hrm? There is no newer release than php-4.3.1. There is RC3, but you
don't want that on a production machine, do you?
Just think how much sexier the code would be if everyone
was able to use superglobals (4.1.0), wouldn't that be
nice?
These features are already included in the last release.
I guess those two mirrors were only included by Philip accidentally. The other mirrors he listed are using seriously old PHPs. You are perfectly up to date.
