download.php

Hvorfor får jeg denne fejl ?

Parse error: parse error, unexpected '\"' in /home/www/download.php on line 8

<?PHP
$dir="/home/download/";
if (isset($_REQUEST["file"])) {
  $file=$dir.$_REQUEST["file"];
  header("Content-type: application/force-download");
  header("Content-Transfer-Encoding: Binary");
  header("Content-length: ".filesize($file));
  header("Content-disposition: attachment; filename="".basename($file).""");
  readfile("$file");
} else {
  echo "No file selected";
}
?>
