Question

我想将一些文件php导出到XLS文件使用类PHPEXcel，我以前没用过。

我的浏览器上的notif： “致命错误：第1124行的C：\ AppServ \ www \ kjjp2 \ Classes \ PHPExcel \ Cell.php中允许的内存大小为25165824字节（尝试分配1056字节）”

代码：

    <?php
    include "config/koneksi.php";

    error_reporting(E_ALL);
    require_once 'Classes/PHPExcel.php';
    // Create new PHPExcel object
    $objPHPExcel = new PHPExcel();

    $query = "SELECT * FROM `tabeldata`";
    $hasil = mysql_query($query);

    // Set properties
    $objPHPExcel->getProperties()->setCreator("Erik")
    ->setLastModifiedBy("Erik")
    ->setTitle("Office 2007 XLSX ")
    ->setSubject("Office 2007 XLSX ")
    ->setDescription("Document for Office 2007 XLSX, generated using PHP classes.")
    ->setKeywords("office 2007 openxml php")
   ->setCategory("Test result file");

    // Add some data
    $objPHPExcel->setActiveSheetIndex(0)
    ->setCellValue('A1', 'Jenis Report')
    ->setCellValue('B1', 'Pembayaran')
    ->setCellValue('C1', 'No')
    ->setCellValue('D1', 'Cabang')
     //and some files


    ->setCellValue('AG1', 'Surveyor');

    $rowNya = 3;
    $no = 0;
    while($row=mysql_fetch_array($hasil)){
    $no = $no +1;
    $objPHPExcel->setActiveSheetIndex(0)

    ->setCellValue("A$rowNya", $row['jenReport'])
    ->setCellValue("B$rowNya", $row['pembayaran'])
     ->setCellValue("C$rowNya", $row['no'])
     ->setCellValue("D$rowNya", $row['cabang'])
    ->setCellValue("E$rowNya", $row['namaSales'])
    ->setCellValue("F$rowNya", $row['jenLaporan'])
          //and some files

    ->setCellValue("AG$rowNya", $row['surveyor']);


    $rowNya = $rowNya + 1;
    }

    // Rename sheet
    $objPHPExcel->getActiveSheet()->setTitle('Simple');

    // Set active sheet index to the first sheet, so Excel opens this as the first sheet
    $objPHPExcel->setActiveSheetIndex(0);

    // Redirect output to a client’s web browser (Excel5)
    header('Content-Type: application/vnd.ms-excel');
    header('Content-Disposition: attachment;filename="database.xls"');
    header('Cache-Control: max-age=0');

    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
    $objWriter->save('php://output');
    exit;
    ?>

Answer 1

PHP正在耗尽可供PHP使用的RAM。您可以设置PHP将在php.ini中使用多少RAM。您目前将此限制设置为24MB，这非常低。尝试增加它。

ini_set('memory_limit', '256M');

Answer 2

PHPExcel因内存饥饿而闻名。该网站讨论了一些解决方法，请参阅http://phpexcel.codeplex.com/discussions/242712?ProjectName=phpexcel

您还可以考虑使用其他库，例如旧的Spreadsheet_Excel_Writer lib（它也有其缺点） http://pear.php.net/package/Spreadsheet_Excel_Writer/redirected
