使用PHPEXCEL lib将XLS转换为CSV，但不将空白行传输到CSV文件

以下代码将XLS文件的每一页转换为CSV文件。 但是我找不到一种方法来阻止它将XLS中的空白行包含到CSV中。

请帮帮我。

function convertXLStoCSV($infile, $outfile) // the function that converts the file { $fileType = PHPExcel_IOFactory::identify($infile); $objReader = PHPExcel_IOFactory::createReader($fileType); $objReader->setReadDataOnly(true); $objPHPExcel = $objReader->load($infile); $writer = PHPExcel_IOFactory::createWriter($objPHPExcel, 'CSV'); $writer->setDelimiter(","); $writer->setEnclosure(""); foreach ($objPHPExcel->getWorksheetIterator() as $workSheetIndex => $worksheet) { $objPHPExcel->setActiveSheetIndex($workSheetIndex); $writer->setSheetIndex($workSheetIndex); $writer->save('converted/' . $outfile ."_" . $worksheet->getTitle() . ".csv"); echo $outfile; echo $infile; } }
