$excel = new ExcelWriter($destinationfilepath); 

// read the source file

 $finalarray= array();

for($m=1;$m<$sourcefilerowcount;$m++)

    { 

           $charvalue='A';

             $temprow=$m+1;

              for($n=0;$n<$destinationcolnum;$n++)
        {

            $data = new Spreadsheet_Excel_Reader($filepath);

                            $finalarray[$n]=$data->val($temprow,$charvalue);

                            $charvalue++;

                    }

             print_r($finalarray)."<br/>";

     $excel->writeLine($finalarray);
  }

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);
