Recognise If A Directory Exists?

[[email protected]]

i need the PHP code for recognising if a directory named "userfiles" exists.

i also need the PHP code for redirecting to another PHP file.

1.is_dir($what_ever);http://www.phpfreaks.com/phpmanual/page/function.is-dir.html

2.header("location: where_ever.php");

ok so i did this:
[code]<?php
if (is_dir('userfiles')){
echo "userfile DOES exist";
else
echo "userfiles does NOT exist";
?>[/code]
and it outputs this:
[b][i]Parse error: syntax error, unexpected T_ELSE in /index.php on line 4[/i][/b]
but i can't see what i did wrong! please help!
