There is no need to explicitly call close() function, because the file is automatically closed in the load() method. If you look at Excel2007.php, where PHPExcel_Reader_Excel2007 is defined, you'll see:

public function load($pFilename)
{
    ...
    $zip = new ZipArchive;

    $zip->open($pFilename);
    ...
    $zip->close();
    return $excel;
}

Just unset your PHPExcel_Reader object, and the data will be removed from memory:

$objReader = PHPExcel_IOFactory::createReader('Excel2003XML');
$objPHPExcel = $objReader->load("Excel2003XMLTest.xml");
...
unset($objPHPExcel);
unset($objReader);
