PHPExcel 中文亂碼的問題

檔案名稱命名亂碼的問題：

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

檔案內容有中文字元的：

header('Content-Type:application/csv;charset=UTF-8');//application/vnd.openxmlformats-officedocument.spreadsheetml.sheetheader('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 檔案名稱亂碼

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