【问题描述】:
这是我的代码,可以在 localhost 中正常工作,以从数据库中生成一个包含数据的 excel 文件,但在托管服务器中它会生成一个空白的 excel 文件:
// Starting the PHPExcel library
$this->load->library('PHPExcel');
//$this->load->library('PHPExcel/IOFactory');
$objPHPExcel = new PHPExcel();
$objPHPExcel->getProperties()->setTitle("export")->setDescription("none");
$objPHPExcel->setActiveSheetIndex(0);
// Field names in the first row
$fields = $query->list_fields();
$col = 0;
foreach ($fields as $field)
{
$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, 1, $field);
$col++;
}
//format the column sizes
$sheet = $objPHPExcel->getActiveSheet();
$cellIterator = $sheet->getRowIterator()->current()->getCellIterator();
$cellIterator->setIterateOnlyExistingCells( true );
/** @var PHPExcel_Cell $cell */
foreach( $cellIterator as $cell ) {
$sheet->getColumnDimension( $cell->getColumn() )->setAutoSize( true );
}
//var_dump($query->result());
//die;
// Fetching the table data
$row = 2;
foreach($query->result() as $data)
{
$col = 0;
foreach($fields as $field)
{
$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $data->$field);
$col++;
}
$row++;
}
$objPHPExcel->setActiveSheetIndex(0);
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="01simple.xlsx"');
header('Cache-Control: max-age=0');
ob_clean();
$objWriter->save('php://output');
【问题讨论】:
-
这表明您在本地服务器上安装了正确的依赖项(模块),并且可能在您的托管服务器上丢失。这将是首先要调查的事情。

也有这个问题。找不到解决方案:-(
