phpexcel導出數據亂碼

使用PHP導出excel文檔，有時候莫名其妙就會出現導出的數據亂碼，現在推薦一個萬能修補大法，話不多說，直接上代碼：
核心就是在處理完數據之後，輸出excel文件之前 添加 ob_end_clean()函數；具體見示例代碼，此處只羅列部分代碼：

foreach ($licenseList as $key => $item) {
 $objPHPExcel->setActiveSheetIndex(0)
     ->setCellValue('A' . ($key + 2), $item["company_name"])
     ->setCellValue('B' . ($key + 2), $item["user_name"])
     ->setCellValue('C' . ($key + 2), $item["order_number"])
     ->setCellValue('D' . ($key + 2), $item['apply_type']==2 ? 'official':'trial')
     ->setCellValue('E' . ($key + 2), $item["license_key"])
     ->setCellValue('F' . ($key + 2), $statusArr[$item['license_status']])->setCellValue('G' . ($key + 2), $item["user_email"])
     ->setCellValue('H' . ($key + 2), date('y/m/d H:i:s', strtotime($item['insert_time'])));
}
 
$objPHPExcel->getActiveSheet()->setTitle('Simple');
$objPHPExcel->setActiveSheetIndex(0);
ob_end_clean();//**解決亂碼核心 就在此處添加此函數**
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="test_list.xls"');
header('Cache-Control: max-age=0');
header('Cache-Control: max-age=1');
header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT');
header('Cache-Control: cache, must-revalidate');
header('Pragma: public');

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
exit;

如果導出來的Excel文字都是亂碼的話，一定要在header()前面加上ob_end_clean()！
