PHPExcel 显示不可读的字符

Question

function districtexcelpdf(){

    ob_start();
    require_once('districtexcel.php');
    $objPHPExcel = new PHPExceldis();       
    $objPHPExcel->districtExcel();

    header('Content-Type: application/vnd.ms-excel');
    header('Content-Disposition: attachment;filename="District_report.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');
    ob_clean();
    $objWriter->save('php://output');
    exit();
}

在上面的代码中我得到了一个不可读的字符。解决此问题需要帮助。

Answer 1

ob_clean();一开始是因为它在使用 ob_start() 之后发送了一个垃圾值；最后 ob_clean();
