สอบถามหน่อยครับ จะทำยังไงให้ มัน read excel ออกมามีเลข 00 ที่อยู่ข้างหน้าออกมาด้วยอ่ะครับ

<?php
header('Content-Type: text/html; charset=utf-8');
if(isset($_FILES['file'])){
	$type = substr($_FILES["file"]['name'], strripos($_FILES["file"]['name'],'.'), strlen($_FILES["file"]['name']));
    $rnd = rand(0,99999); 
	$uniqueName = $rnd.$type; 
	move_uploaded_file($_FILES['file']['tmp_name'],$uniqueName);


	require_once 'PHPExcel/Classes/PHPExcel.php';

	/** PHPExcel_IOFactory - Reader */
	include 'PHPExcel/Classes/PHPExcel/IOFactory.php';
	$objPHPExcel = new PHPExcel();
 
	$inputFileName = $uniqueName; 
	$inputFileType = PHPExcel_IOFactory::identify($inputFileName);  
	$objReader = PHPExcel_IOFactory::createReader($inputFileType); 
	
	$objReader->setReadDataOnly(true);  
	$objPHPExcel = $objReader->load($inputFileName);  
	$objWorksheet = $objPHPExcel->setActiveSheetIndex(0);
	$highestRow = $objWorksheet->getHighestRow();
	$highestColumn = $objWorksheet->getHighestColumn();

	$headingsArray = $objWorksheet->rangeToArray('A1:'.$highestColumn.'1',null, true, true, true);
	$headingsArray = $headingsArray[1];

	$r = -1;
	$namedDataArray = array();
	for ($row = 2; $row <= $highestRow; ++$row) {
		
		$dataRow = $objWorksheet->rangeToArray('A'.$row.':'.$highestColumn.$row,null, true, true, true);
		
		if ((isset($dataRow[$row]['A'])) && ($dataRow[$row]['A'] > '')) {
			++$r;
			foreach($headingsArray as $columnKey => $columnHeading) {
				$namedDataArray[$r][$columnHeading] = $dataRow[$row][$columnKey];	
			}
		}
	}print_r($namedDataArray);	
}

?>
