Answer 1

Check the documentation here:

IMPORTANT NOTICE

{php} tags are deprecated from Smarty, and should not be used. Put your PHP logic in PHP scripts or plugin functions instead. Note

As of Smarty 3.1 the {php} tags are only available from SmartyBC.

If you're using Smarty 3.0x, it should work. If you're using Smarty 3.1, you have to install the SmartyBC class (Backwards Compatibility Wrapper) for the use of the {php}-Tag.

But where possible try to follow Smartys advice: Put PHP logic in PHP scripts, and not into the Smarty templates.
