Software version numbers

A quick question...

I had thought that the version of PHP we were using - installed using FoxServ - was version 5, but if I use the phpinfo() command it is telling me it is version 4.2.2. Are there any implications in upgrading to version 5? i.e. will everything still work as it does?

Also, for MySQL - the version number is 4.0.1. This seems to be giving me problems (as described in the thread for 6A1) which can be resolved by running a file (mysql_fix_privilege_tables.sql) BUT this apparently works best with a newer version of MySQL. Are there likely to be problems with upgrading?

How 'friendly' is the Apache/PHP/MySQL setup in this regard?

FoxServ is still 4. XAMPP is 5.

There are differences - for example you have to use $_POST to catch a variable, whereas with 4 it is automatically available, i.e. if you use "name" in a form in V4 then on the next page $name will be available. With 5 you have to use $_POST to get the variable.

Just uninstall foxserv (dump mysql files first so you can import again) and install XAMPP. Move your files over to the xammp directory. You'll have to code in a few lines here and there. XAMPP install much easier and is better than Foxserv.

I'll run your prac on watever version you used.
