phpExcel 正确读取excel表格时间

 

利用phpExcel读取excel文件，读取出来的时间列出现5位数字，并不是想要的时间(不知道为啥)，在网上搜了一个excelTime的函数可以正确转化时间

error_reporting(E_ALL);
date_default_timezone_set('Asia/shanghai');
/** PHPExcel_IOFactory */
require_once '../Classes/PHPExcel/IOFactory.php';
$inputFileName = '6081076641077444758.xls';
$objReader = new PHPExcel_Reader_Excel5();
$objPHPExcel = $objReader->load($inputFileName);
$sheet = $objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow(); // 取得总行数
$highestColumn = $sheet->getHighestColumn(); // 取得总列数
$tempArray = array();
for($j=2;$j<=$highestRow;$j++){
   for($k='A';$k<=$highestColumn;$k++){ 
    if($k=='M'||$k=='O') //M列和O列是时间
		$tempArray[] = excelTime($objPHPExcel->getActiveSheet()->getCell("$k$j")->getValue());
	else
		$tempArray[] = $objPHPExcel->getActiveSheet()->getCell("$k$j")->getValue();
	}
	print_r($tempArray);
	unset($tempArray);
}

function excelTime($date, $time = false) {
	if(function_exists('GregorianToJD')){
		if (is_numeric( $date )) {
		$jd = GregorianToJD( 1, 1, 1970 );
		$gregorian = JDToGregorian( $jd + intval ( $date ) - 25569 );
		$date = explode( '/', $gregorian );
		$date_str = str_pad( $date [2], 4, '0', STR_PAD_LEFT )
		."-". str_pad( $date [0], 2, '0', STR_PAD_LEFT )
		."-". str_pad( $date [1], 2, '0', STR_PAD_LEFT )
		. ($time ? " 00:00:00" : '');
		return $date_str;
		}
	}else{
		$date=$date>25568?$date+1:25569;
		/*There was a bug if Converting date before 1-1-1970 (tstamp 0)*/
		$ofs=(70 * 365 + 17+2) * 86400;
		$date = date("Y-m-d",($date * 86400) - $ofs).($time ? " 00:00:00" : '');
	}
  return $date;
