Solution to garbled characters when exporting phpexcel to xls file

The solution is as follows:

<?php
include &#39;global.php&#39;;
$ids = $_GET[&#39;ids&#39;];

$sql = "select * from crm_cost_end where id in ( {$ids} )";
$result = $db->findAll($sql);
//echo $result[1][&#39;sn&#39;];

//创建一个excel对象
$objPHPExcel = new PHPExcel();
// Set properties

$objPHPExcel->getProperties()->setCreator("ctos")
    ->setLastModifiedBy("ctos")
    ->setTitle("Office 2007 XLSX Test Document")
    ->setSubject("Office 2007 XLSX Test Document")
    ->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.")
    ->setKeywords("office 2007 openxml php")
    ->setCategory("Test result file");

//set width
$objPHPExcel->getActiveSheet()->getColumnDimension(&#39;A&#39;)->setWidth(8);
$objPHPExcel->getActiveSheet()->getColumnDimension(&#39;B&#39;)->setWidth(10);

//设置行高度
$objPHPExcel->getActiveSheet()->getRowDimension(&#39;1&#39;)->setRowHeight(22);

$objPHPExcel->getActiveSheet()->getRowDimension(&#39;2&#39;)->setRowHeight(20);

// Miscellaneous glyphs, UTF-8

for ($i = 0; $i < count($result) - 1; $i++) {
  $objPHPExcel->getActiveSheet(0)->setCellValue(&#39;A&#39; . ($i + 3), $result[$i][&#39;id&#39;]);

  $objPHPExcel->getActiveSheet()->getRowDimension($i + 3)->setRowHeight(16);
}


// Rename sheet
$objPHPExcel->getActiveSheet()->setTitle(&#39;订单汇总表&#39;);


// Set active sheet index to the first sheet, so Excel opens this as the first sheet
$objPHPExcel->setActiveSheetIndex(0);


// Redirect output to a client&#39;s web browser (Excel5)
<span style="color:#ff0000;">ob_end_clean();//清除缓冲区,避免乱码</span>
header(&#39;Content-Type: application/vnd.ms-excel&#39;);
header(&#39;Content-Disposition: attachment;filename="订单汇总表(&#39; . date(&#39;Ymd-His&#39;) . &#39;).xls"&#39;);
header(&#39;Cache-Control: max-age=0&#39;);

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, &#39;Excel5&#39;);
$objWriter->save(&#39;php://output&#39;);
?>

Add the ob_end_clean() function in front of header() to clear the buffer, so that there will be no garbled characters!
