使用php内部自带函数实现

1、使用DateTime::diff 实现计算 参考阅读>>PHP DateTime::diff()

上代码:

1
2
3
4
5
6
7
<?php 
$start = "2016-05-25";
$end = "2016-05-23";

$datetime_start = new DateTime($start);
$datetime_end = new DateTime($end);
var_dump($datetime_start->diff($datetime_end));

结果

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
object(DateInterval)[3]
public 'y' => int 0
public 'm' => int 0
public 'd' => int 2
public 'h' => int 0
public 'i' => int 0
public 's' => int 0
public 'weekday' => int 0
public 'weekday_behavior' => int 0
public 'first_last_day_of' => int 0
public 'invert' => int 1
public 'days' => int 2
public 'special_type' => int 0
public 'special_amount' => int 0
public 'have_weekday_relative' => int 0
public 'have_special_relative' => int 0

由结果我们知道,想要得出时间差,可以用下面方法实现

1
2
3
4
5
6
7
$start = "2016-05-25";
$end = "2016-05-23";

$datetime_start = new DateTime($start);
$datetime_end = new DateTime($end);
$days = $datetime_start->diff($datetime_end)->days;
echo "时间差是:$days";

最终结果为

1
时间差是:2

2.date_create()、date_diff()实现

1
2
3
4
5
6
7
$start = "2016-05-25";
$end = "2016-05-23";

$datetime_start = date_create($start);
$datetime_end = date_create($end);
$days = date_diff($datetime_start, $datetime_end);
var_dump($days);

打印结果

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
object(DateInterval)[3]
public 'y' => int 0
public 'm' => int 0
public 'd' => int 2
public 'h' => int 0
public 'i' => int 0
public 's' => int 0
public 'weekday' => int 0
public 'weekday_behavior' => int 0
public 'first_last_day_of' => int 0
public 'invert' => int 1
public 'days' => int 2
public 'special_type' => int 0
public 'special_amount' => int 0
public 'have_weekday_relative' => int 0
public 'have_special_relative' => int 0

具体实现:

1
2
3
4
5
6
7
$start = "2016-05-25";
$end = "2016-05-23";

$datetime_start = date_create($start);
$datetime_end = date_create($end);
$days = date_diff($datetime_start, $datetime_end)->days;
echo "时间间隔是:$days";

结果

1
时间间隔是:2
