upgrading locally - what php version should I use?

[piker]

I would like to do an upgrade (or fresh install) locally on my PC.With Uniform Server (which I always use)I have a choice of which PHP versions to use.Should I use a 5.2.9 php version (which my host uses now) or a 5.3.0 php version (which, no doubt, will be the next upgrade for the host and is fully compatible with zen 1.3.9)?
If I went ahead and worked on my site locally, using php 5.3.0, will I come up against any problems uploading it to the Hosts server that still currently uses 5.2.9?

It is always best to develop locally with the same php, mysql versions as the live site will be

Thanks kobra. At least I know with 1.3.9 there won't be any dramas when they do upgrade. Cheers.
