Interesting phpversion() thing.

I just upgraded to 4.3.5. I double checked and made sure I put everything in the right place. If I run php or php-cli from the command line and the script has phpversion() in it, it returns the correct string, i.e. 4.3.5. If, however, I pull the same script up in a browser it gives me 4.3.4. I've tried everything, clearing caches, etc. Can't seem to get it to do what I expect. Any one else see this? Nick
