我有PHPExcel功能的問題，這是我的代碼：

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

我使用的開關列，其中我需要一個不同的單元格的格式。

列G和H我需要格式2015.10.05（yyyy.mm.dd）並且列L 2015.10.05 12:03（yyyy.mm.dd H：i）。

函數getStyle（）不起作用，並返回相同的值。如果輸出爲= datevalue，這是excel函數，一切正常，但它不適用於時間。

此外，如果我在Excel中按編輯單元格，然後按回車鍵，該日期轉換爲正常的日期爲Excel和所有工作正常。

所以，問題是輸出格式。我怎樣才能定義它？對於其他列，例如數字，一切正常。

您需要將日期和日期/時間轉換爲MS Excel序列化日期時間戳。MS Excel不會自動將字符串轉換爲日期，也不會簡單地設置樣式更改實際值（字符串在你的情況下）以任何方式存儲在單元格中。

PHPExcel在PHPExcel_Shared_Date類中提供了幾種不同的方法，可以讓您執行這些轉換。

$dto = new DateTime($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);
