我有大量的Excel工作表,我希望能够使用PHPExcel读入MySQL.

我正在使用最近的补丁,它允许您在不打开整个文件的情况下读取工作表.这样我就可以一次阅读一个工作表.

但是,一个Excel文件大27MB.我可以成功阅读第一个工作表,因为它很小,但第二个工作表是如此之大,以至于22:00启动进程的cron作业在上午8:00没有完成,工作表很简单.

是否有任何方法可以逐行读取工作表,例如:

$inputFileType = 'Excel2007';
$inputFileName = 'big_file.xlsx';
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$worksheetNames = $objReader->listWorksheetNames($inputFileName);

foreach ($worksheetNames as $sheetName) {
    //BELOW IS "WISH CODE":
    foreach($row = 1; $row <=$max_rows; $row+= 100) {
        $dataset = $objReader->getWorksheetWithRows($row, $row+100);
        save_dataset_to_database($dataset);
    }
}

@mark,我使用您发布的代码创建以下示例:

function readRowsFromWorksheet() {

    $file_name = htmlentities($_POST['file_name']);
    $file_type = htmlentities($_POST['file_type']);

    echo 'Read rows from worksheet:<br />';
    debug_log('----------start');
    $objReader = PHPExcel_IOFactory::createReader($file_type);
    $chunkSize = 20;
    $chunkFilter = new ChunkReadFilter();
    $objReader->setReadFilter($chunkFilter);

    for ($startRow = 2; $startRow <= …

我不明白.XSLX表大约3MB,甚至1024MB的RAM还不足以让PHPExcel将其加载到内存中？

我可能在这里做了一些可怕的错误:

function ReadXlsxTableIntoArray($theFilePath)
{
    require_once('PHPExcel/Classes/PHPExcel.php');
    $inputFileType = 'Excel2007';
    $objReader = PHPExcel_IOFactory::createReader($inputFileType);
    $objReader->setReadDataOnly(true);
    $objPHPExcel = $objReader->load($theFilePath);
    $rowIterator = $objPHPExcel->getActiveSheet()->getRowIterator();
    $arrayData = $arrayOriginalColumnNames = $arrayColumnNames = array();
    foreach($rowIterator as $row){
        $cellIterator = $row->getCellIterator();
        $cellIterator->setIterateOnlyExistingCells(false); // Loop all cells, even if it is not set
        if(1 == $row->getRowIndex ()) {
            foreach ($cellIterator as $cell) {
                $value = $cell->getCalculatedValue();
                $arrayOriginalColumnNames[] = $value;
                // let's remove the diacritique
                $value = iconv('UTF-8', 'ISO-8859-1//TRANSLIT', $value);
                // and white spaces
                $valueExploded = explode(' ', $value);
                $value = …
