用PHP做一个导入excel功能,发现读取excel时间列的时候总是数据不对,去网上查找了这个函数,转换了一下就好了,真尼玛迷茫了,什么情况,先记录一下,以后再研究吧。
函数如下:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19

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
