我想在我的项目中使用PHPSpreadsheet库将数据导出到excel文件,但是当我尝试打开文件时,此错误显示:excel无法打开文件,因为文件格式或文件扩展名无效。确认文件未损坏
注意:我在项目中使用MVC 因此控制器中的代码如下:
protected function Excel($view, $variables = [])
{
require_once PATH_LIBRARY_FOLDER.'PhpSpreadsheet\vendor\autoload.php';
ob_start();
// Note: make new Spreadsheet object
$spreadsheet = new Spreadsheet();
// Note: get current active sheet (frist sheet)
$sheet = $spreadsheet->getActiveSheet();
$sheet->setCellValue('A1', 'Hello World !');
extract($variables);
include($this->viewPath.$view.'.php');
// Note: set the header to define it is excel file
header("Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
// Note: set the header to define excel file name
header("Content-Disposition: attachment;filename=\"filename.xlsx\"");
header("Cache-Control: max-age=0");
// Note: create IOFactory object
$writer = IOFactory::createWriter($spreadsheet, 'xlsx');
ob_get_clean();
$writer->save('php:://output');
exit();
}
当我以文本形式打开文件时,发现此错误:
致命错误:未捕获的PhpOffice \ PhpSpreadsheet \ Writer \ Exception:无法打开php :: //输出以进行编写。在C:\ xampp \ htdocs \ GL_App \ Library \ PhpSpreadsheet \ vendor \ phpoffice \ phpspreadsheet \ src \ PhpSpreadsheet \ Writer \ Xlsx.php:218

更改此代码行
$writer->save('php:://output');
到
$writer->save('php://output');
应该可以。另外,如何将数据传递到Excel工作表?您的数据可能已损坏。
请在autoload.php之后将其插入您的代码中
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

我有同样的问题,我的解决方案在这里。只需将代码放在下面:
ob_end_clean();
代码:
ob_end_clean();
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="'. $filename );
header('Cache-Control: max-age=0');
$writer->save('php://output'); // download file
