I receive a 'Parse error'!

Parse error: syntax error, unexpected T_STRING in /home/michelz/public_html/valdemedia/smileys.php on line 11

My .php file:

<?php
header( 'Location: http://nbjmp.com/click/?o=42&a=5456&c=26957&s=358&subid=<? echo “$k1w\n”; ?>' ) ;
?>

<?php ob_start();

if(isset($_REQUEST[’kw’]))

{
$kw = preg_replace(’%20’,’ ‘,$_REQUEST[’kw’]).”";

$k1w = urldecode( $_REQUEST[’kw’] ).”";

}

else

{

$k1w = NULL;

}

?>


It looks like that error is referring to line I made bold!
I don't know what's wrong with my file, what change do I need to make to get my file work?
Many thanks!

Mike

$kw = preg_replace('%20','',$_REQUEST['kw']);

You have some weird ass quotes too. Never seen them before.
