excel时间

function exceltimtetophp($days,$time=false)
{
if(is_numeric($days))
{

//凯撒日计数，要把我们运用的从1970年开始的日期运用函数GregorianToJD（），转换为凯撒日计数
$jd = GregorianToJD(1, 1, 1970);  
$gregorian = JDToGregorian($jd+intval($days)-25569);
$gregorian = strtotime($gregorian);
$gregorian = date("Y/m/d",$gregorian);
// $myDate = explode(\'\\\\\',$gregorian);
// $myDateStr = str_pad($myDate[2],4,\'0\', STR_PAD_LEFT)."-".str_pad($myDate[0],2,\'0\',STR_PAD_LEFT)."-".str_pad($myDate[1],2,\'0\', STR_PAD_LEFT).($time?"00:00:00":\'\\\\\');
return $gregorian;
}
return $time;
}

$val = \'42930\'; //excel读取的内容
$val = exceltimtetophp($val);
$preg_date = \'/^(\\d{4})\\/(0\\d{1}|[1-9]{1}||1[0-2])\\/(0\\d{1}|[1-9]{1}|[12]\\d{1}|3[01])$/\'; //正则验证时间：当时间为 2017/01/01或2017/1/1或2017/11/11这种的都通过
$status_date = trim($val);
echo $status_date;
preg_match($preg_date,$status_date,$matches);

var_dump($matches);

 结果如下：
