create a php file with the content:
and you will get a lot of info on you're installation, including the php-version.
as of version 4.1.0 variables submitted to the page with the post-method are available in the array $_POST before version 4.1.0 this was $HTTP_POST_VARS (which is still available, but deprecated).
phpmyadmin might still be using the $HTTP_POST_VARS and therefore it will work on older versions as well.
if you installed php from the same cd, the version is ofcourse the same and all of my typing here is sort of useless :roll:
one last note, latest version is 4.2.2, so if you've got version 4.4..... can I have a copy???
