php - 使用 PHPExcel 函数将日期和日期时间写入 Excel 中作为文本

Question

我的 PHPExcel 函数有问题，这是我的代码:

$objWriter->save('php://output');
exit;

我正在使用列开关，我需要不同的单元格格式。

G 列和 H 列我需要格式 2015.10.05 (yyyy.mm.dd) 以及 L 列 2015.10.05 12:03 (yyyy.mm.dd H:i)。

函数 getStyle() 不起作用，并返回相同的值。如果输出为=datevalue，这是excel函数，一切都可以，但它不能与时间一起工作。

此外，如果我按 Excel 中的编辑单元格并按 Enter，该日期将转换为 Excel 的正常日期，并且一切正常。

所以，问题出在输出格式上。我该如何定义它？对于其他列，例如数字，一切都可以。

Answer 1

您需要将日期和日期/时间转换为 MS Excel 序列化日期时间戳....MS Excel 不会自动将字符串转换为日期，也不会简单地设置样式来更改实际值(中的字符串)您的案例)以任何方式存储在单元格中。

PHPExcel 在 PHPExcel_Shared_Date 类中提供了几种不同的方法，可以让您执行这些转换。

$dto = new DateTime($result[$rowCount][$value]);
$dateVal = PHPExcel_Shared_Date::PHPToExcel($dto);
$objPHPExcel->getActiveSheet()->getStyle($column.$cell)
    ->getNumberFormat()
    ->setFormatCode("yyyy.mm.dd h:mm");
$objPHPExcel->getActiveSheet()->setCellValue($column.$cell, $dateVal);
