Question

我制作了一个脚本，我收到以下错误。如果将内存大小升级到7g仍然是错误。所以我试图附加10000条记录并保存，然后去下一万条来解决它，有效，但仍然出错。

有没有办法刷新工作簿或其他方法？

日Thnx！

the awnser：

PHPExcel_Settings::setCacheStorageMethod($cacheMethod, $cacheSettings);   
$cacheMethod = PHPExcel_CachedObjectStorageFactory:: cache_to_discISAM;
$cacheSettings = array( 
    'dir' => '/home/domains/xxxx.nl/public_html/xxxxx'
);



require_once 'PHPExcel.php';
require_once 'PHPExcel/Writer/Excel2007.php';
require_once 'PHPExcel/IOFactory.php';



$counter = $result->num_rows;//159920
$spreadsheet = new PHPExcel();
$spreadsheet->setActiveSheetIndex(0);
$worksheet = $spreadsheet->getActiveSheet();


//header
$worksheet->setCellValueExplicit('A' . 1, 'Filename', PHPExcel_Cell_DataType::TYPE_STRING);
etc
etc

$rownr = 2;
$counterN = 0;
while ($row = mysqli_fetch_assoc($result)) {  
    $worksheet->setCellValueExplicit('A' . $rownr, utf8_encode($row['filename']), PHPExcel_Cell_DataType::TYPE_STRING);
    etc
    etc

    if( $counterN == 10000 ){

        $objWriter = new PHPExcel_Writer_Excel2007($spreadsheet);
        $objWriter->save('test.xlsx');

        $objPHPExcel = PHPExcel_IOFactory::load("test.xlsx");
        $objPHPExcel->setActiveSheetIndex(0);
        $row = $objPHPExcel->getActiveSheet()->getHighestRow()+1;
        $counterN = 0;
    }
    $counterN++;

}

$objWriter = new PHPExcel_Writer_Excel2007($spreadsheet);
$objWriter->save('test.xlsx');

如果没有足够的内存来处理大量单元格，那么推荐的减少内存使用量的方法是使用单元格缓存，如4.2.1.中所述开发人员文档。
