问题描述

我对PHPExcel函数有问题，这是我的代码:

我正在为列使用开关，在这里我需要其他单元格格式.

G列和H列需要格式2015.10.05(yyyy.mm.dd)，L列需要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)，则一切正常，但是随着时间的流逝将无法正常工作.

此外，如果我按excel中的edit单元格并按Enter，则该日期将转换为excel的正常日期，并且一切正常.

因此，问题出在输出格式化上.我该如何定义?对于其他列，例如数字，一切正常.

解决方案

您需要将日期和日期/时间转换为MS Excel序列化的日期时间戳....MS Excel不会自动为您将字符串转换为日期，只是简单地设置样式也不会以任何方式更改存储在单元格中的实际值(在您的情况下为字符串).

PHPExcel在PHPExcel_Shared_Date类中提供了几种不同的方法，使您可以进行这些转换.

$dto = new DateTime($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);

I'm using switch for columns, where I need a different cell format.

Column G and H I need format 2015.10.05 (yyyy.mm.dd) And for column L 2015.10.05 12:03 (yyyy.mm.dd H:i).

Function getStyle() doesn't work, and returns the same value. If output as =datevalue, which is excel function, all is ok, but it doesn't work with time.

Also, if I press edit cell in excel and press enter, that date converts to normal date for excel and all works fine.

So, the problem is with output formatting. How can I define it? For other columns, for example for numbers, all is ok.

解决方案

You need to convert your dates and date/times to an MS Excel serialized datetime stamp.... MS Excel does not automagically convert strings to dates for you, nor does simply setting a style change the actual value (a string in your case) that's stored in the cell in any way.

PHPExcel provides several different methods in the PHPExcel_Shared_Date class that will let you do these conversions.

$dto = new DateTime($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);
