<?PHP vs. <?php: does it matter?

[pixelcop]

This is probably one of the dumbest questions ever asked here, but I'd really like to know and did a search before ...

In (X)HTML tags should be lowercase, but for PHP I often see <?PHP instead of <?php - even if the rest of the site's tags are all lowercase.

Is there any reason to use uppercase for this tag? I guess no, or ...?

nope you can use <% and ?> and that would be valid. depending if you php.ini was set up right...

it doesn't make any different if its caps or not.

but I wouldn't recommend using <% cause if you'd want to learn asp further on, you'd conflict with the two languages, so, stick with <?php

Thanks a lot for your help!
