//Soluzione come indicato di seguito:

<?php
include 'global.php';
$ids = $_GET['ids'];
$sql = "select * from crm_cost_end where id in ( {$ids} )";
$result = $db->findAll($sql);
//echo $result[1]['sn'];
//创建一个excel对象
$objPHPExcel = new PHPExcel();
// Set properties 
$objPHPExcel->getProperties()->setCreator("ctos")
    ->setLastModifiedBy("ctos")
    ->setTitle("Office 2007 XLSX Test Document")

//}} 
$objPHPExcel->getActiveSheet()->mergeCells('A1:J1');
// impostare il contenuto dell'intestazione della tabella 
$objPHPExcel->setActiveSheetIndex(0)
    ->setCellValue('A1', 'Riepilogo dati ordine Tempo:' . date('Y-m-d H:i:s'))
    ->setCellValue('A2', 'ID ordine')

    ->setCellValue('J2', 'Nota di consegna PMC');
// Glifi vari, UTF-8 
for ($i = 0; $i < count($result) - 1; $i++) {
  $objPHPExcel->getActiveSheet(0)->setCellValue('A' . ($i + 3), $result[$i]['id']);
  $objPHPExcel->getActiveSheet(0)->setCellValue('B' . ($i + 3), $result[$i]['realname']);
  $objPHPExcel->getActiveSheet(0)->setCellValue('C' . ($i + 3), $result[$i]['customer_name']);

  $objPHPExcel->getActiveSheet(0)->setCellValue('J' . ($i + 3), $result[$i]['delivery_memo']);
  $objPHPExcel->getActiveSheet()->getStyle('A' . ($i + 3) . ':J' . ($i + 3))->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER);
  $objPHPExcel->getActiveSheet()->getStyle('A' . ($i + 3) . ':J' . ($i + 3))->getBorders()->getAllBorders()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
  $objPHPExcel->getActiveSheet()->getRowDimension($i + 3)->setRowHeight(16);
}
// Rinomina la scheda 
$objPHPExcel->getActiveSheet()->setTitle('Riepilogo ordini');
// Imposta l'indice della scheda attiva alla prima scheda, in modo che Excel la apra come la prima scheda 
$objPHPExcel->setActiveSheetIndex(0);
// Reindirizza l'output al browser web del client (Excel5) 
<span style="color:#ff0000;">ob_end_clean();//pulisci il buffer, evita i caratteri sbagliati</span>
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="Riepilogo ordini(' . date('Ymd-His') . ').xls"');
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
?>

Aggiungi la funzione ob_end_clean() prima di header(), per pulire il buffer, in questo modo non ci saranno caratteri sbagliati!

Questo è tutto il contenuto che ti ho portato il problema di soluzione perfetta per phpexcel exportato in xls file con caratteri sbagliati, spero che possiate sostenere e urlare il tutorial!
