Are there any issues with settings when upgrading from PHP 5.1.2 to 5.3.8?

I have never upgraded my version of PHP but feel I need to to use some of the new abilities. So I was wondering if there is any risk of losing my settings or even perhaps breaking the functionality of my code when upgrading?

Yes. The best way to find out is to deploy your application in a test environment with the new version of PHP and thoroughly test it before upgrading PHP on your production server.

Yes. The biggest problems I've seen is with old code that uses assignment by reference functions

$sFoo =& $sBar;

99% of the time you can change the code to 

$sFoo = $sBar;

and it works great--Your mileage may vary

Also 5.2 defaults to having the short_open_tag being off. if your code all begins with <?php instead of just <? I suggest keeping this off to promote good programming, if not you'll need to change it (recommended) or change the short_open_tag to on in your php.ini

There's a section available on the PHP website that feature changes between versions, including any backwards incompatible features.
You'll likely have to check the 5.1->5.2 and the 5.2->5.3 pages on the left navigation bar.
