In PHP Spreadsheet, the date or time values are stored in an excel sheet in the form of timestamp which is a floating point value. So in order to store date/time in a human-readable format, need to calculate the correct excel timestamp and finally set a number format mask.
Example:
<?php // PHP program to set a date time value in excel sheet require_once ( 'vendor/autoload.php' ); use PhpOffice\PhpSpreadsheet\Spreadsheet; use PhpOffice\PhpSpreadsheet\Writer\Xlsx; // Creates New Spreadsheet $spreadsheet = new Spreadsheet(); // Retrieve the current active worksheet $sheet = $spreadsheet ->getActiveSheet(); // Set the number format mask so that the excel timestamp // will be displayed as a human-readable date/time $spreadsheet ->getActiveSheet()->getStyle( 'A1' ) ->getNumberFormat() ->setFormatCode( \PhpOffice\PhpSpreadsheet\Style\NumberFormat::FORMAT_DATE_DATETIME ); // Get current date and timestamp // Convert to an Excel date/time $dateTime = time(); $excelDateValue = \PhpOffice\PhpSpreadsheet\Shared\ Date ::PHPToExcel( $dateTime ); // Set cell A1 with the Formatted date/time value $sheet ->setCellValue( 'A1' , $excelDateValue ); // Write an .xlsx file $writer = new Xlsx( $spreadsheet ); // Save .xlsx file to the current directory $writer ->save( 'gfgdate.xlsx' ); ?> |
