Backtick call appends extra space

[Martin]

Look at the following code:
<?php
$year = `date +
%Y`;
echo "(".$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.
