Solution as follows:

<?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'];
//Create an excel object
$objPHPExcel = new PHPExcel();
// Set properties 
$objPHPExcel->getProperties()->setCreator("ctos")
    ->setLastModifiedBy("ctos")

// Defina o índice da folha ativa para a primeira folha, para que o Excel a abra como a primeira folha 
$objPHPExcel->setActiveSheetIndex(0);
// Redirecione a saída para o navegador da web do cliente (Excel5) 
<span style="color:#ff0000;">ob_end_clean();//Limpe o buffer, evite caracteres estranhos</span>
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="Tabela de Resumo de Pedidos(' . date('Ymd-His
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5);
$objWriter->save('php://output');
?>

Adicione a função ob_end_clean() antes do header(), limpe o buffer, assim não haverá caracteres estranhos!

Isso é tudo que o editor trouxe para você para resolver o problema de caracteres estranhos ao exportar para o arquivo xls do phpexcel, esperamos que você apoie e grite o tutorial!
