Look at the following code:

echo "(".$year.")";

The output is
(2008 )
There is an extra space after the "2008". Why is that, and what can I
do about it?
It's not a space, it's a linefeed (look at the source generated; the linefeed is converted to a space for presentation because of HTML whitespace rules). This will happen with pretty much any command line utility; they all must print a linefeed after their output to get your prompt on the following line.
And like Heiko Richler said - trim() the output and you shouldn't have any problems.
