php更新修改excel中的内容例子

本例子不是读取Excel或生成新的Excel，而是读取现有的Excel文件，然后修改Excel中的数据,就像修改mysql中数据一样的哦。

canRead($dir . $templateName)) {
    $PHPReader = new PHPExcel_Reader_Excel5();
    if (!$PHPReader->canRead($dir . $templateName)) {
        echo '无法识别的Excel文件！';
        return false;
    }
}
//读取Excel
$PHPExcel = $PHPReader->load($dir . $templateName);
//读取工作表1
$currentSheet = $PHPExcel->getSheet(0);
$currentSheet->setCellValue('B13', iconv('gbk', 'utf-8', $txt)); //表头赋值//
//实例化Excel写入类
$PHPWriter = new PHPExcel_Writer_Excel2007($PHPExcel);
ob_start();
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header('Content-Disposition:attachment;filename="' . $outputFileName . '"'); //输出模板名称
header("Content-Transfer-Encoding: binary");
header("Last-Modified:" . gmdate("D, d M Y H:i:s") . " GMT");
header('Pragma: public');
header('Expires: 30');
header('Cache-Control: public');
$PHPWriter->save('php://output');
?>
