您能否指导我或为我提供一些使用PHPExcel库执行CSV导出和导入的示例代码？
Excel导出和导入很好，但我也需要CSV导出/导入。我还有其他CSV导出和导入方法，但也可以通过PHPExcel完成吗？

将CSV文件导入PHPExcel对象
$inputFileType = 'CSV';
$inputFileName = 'testFile.csv';
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($inputFileName);
从PHPExcel对象导出CSV文件
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'CSV');
$objWriter->save('testExportFile.csv');
修改
如何阅读行和单元格：
$worksheet = $objPHPExcel->getActiveSheet();
foreach ($worksheet->getRowIterator() as $row) {
echo 'Row number: ' . $row->getRowIndex() . "\r\n";
$cellIterator = $row->getCellIterator();
$cellIterator->setIterateOnlyExistingCells(false); // Loop all cells, even if it is not set
foreach ($cellIterator as $cell) {
if (!is_null($cell)) {
echo 'Cell: ' . $cell->getCoordinate() . ' - ' . $cell->getValue() . "\r\n";
}
}
}
如何写入PHPExcel对象： 您没有说明数据来自何处：以下是如何从MySQL查询中执行此操作
$query = sprintf("SELECT firstname, lastname, age, date_of_birth, salary FROM employees WHERE firstname='%s' AND lastname='%s'",
mysql_real_escape_string($firstname),
mysql_real_escape_string($lastname));
$result = mysql_query($query);
$row = 1;
$objPHPExcel->getActiveSheet()->setCellValue('A'.$row, 'First Name')
->setCellValue('B'.$row, 'Last Name')
->setCellValue('C'.$row, 'Age')
->setCellValue('D'.$row, 'Date of birth')
->setCellValue('E'.$row, 'Salary');
$row++;
while ($rec = mysql_fetch_assoc($result)) {
$objPHPExcel->getActiveSheet()->setCellValue('A'.$row, $rec['firstname'])
->setCellValue('B'.$row, $rec['lastname'])
->setCellValue('C'.$row, $rec['age'])
->setCellValue('D'.$row, PHPExcel_Shared_Date::stringToExcel($rec['date_of_birth']))
->setCellValue('E'.$row, $rec['salary']);
$objPHPExcel->getActiveSheet()->getStyle('D'.$row)->getNumberFormat()->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_DATE_XLSX15);
$objPHPExcel->getActiveSheet()->getStyle('E'.$row)->getNumberFormat()->setFormatCode('£#,##0.00');
$row++;
}

我一直在寻找同样的事情。 Excel CSV并不总是使用引号分隔符并使用“”来转义引号，因为算法可能是80年代或者其他东西。在PHP.NET的评论部分查看了几个.csv解析器之后，我看到了甚至使用了回调或eval'd代码的那些解析器，它们要么没有按需工作，要么根本就没有工作。所以，我为此编写了自己的例程，它们在最基本的PHP配置中工作。数组键可以是数字键，也可以命名为标题行中给出的字段。希望这可以帮助。
