PHPExcel 在LINUX环境中导出乱码的问题解决

文件名命名乱码的问题：

$ua = $_SERVER['HTTP_USER_AGENT'];
if(preg_match('/MSIE/',$ua)) {
  $file_name = str_replace('+','%20',urlencode($file_name));
}

文件内容有中文字符的：

header('Content-Type:application/csv;charset=UTF-8');//application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
header('Content-Disposition: attachment;filename="' . $file_name . '"');
header('Cache-Control: No-cache');
    
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'CSV');
    
//set CSV file to UTF-8
$objWriter->setUseBOM(true);

IE 文件名乱码

        $ua = $_SERVER['HTTP_USER_AGENT'];
if(preg_match('/MSIE/',$ua)) {
  $outputFileName = str_replace('+','%20',urlencode($outputFileName));
