PHP 标准的日期格式
date("Y-m-d H:i:s");
PHP 简单的日期加减计算
<?php
date_default_timezone_set(‘PRC‘); //默认时区
echo "今天:",date("Y-m-d",time()),"
";
echo "今天:",date("Y-m-d",strtotime("18 june 2008")),"
";
echo "昨天:",date("Y-m-d",strtotime("-1 day")),"
";
echo "明天:",date("Y-m-d",strtotime("+1 day")),"
";
echo "一周后:",date("Y-m-d",strtotime("+1 week")),"
";
echo "一周零两天四小时两秒后:",date("Y-m-d G:H:s",strtotime("+1 week 2 days 4 hours 2 seconds")), "
";
echo "下个星期四:",date("Y-m-d",strtotime("next Thursday")),"
";
echo "上个周一:".date("Y-m-d",strtotime("last Monday"))."
";
echo "一个月前:".date("Y-m-d",strtotime("last month"))."
";
echo "一个月后:".date("Y-m-d",strtotime("+1 month"))."
";
echo "十年后:".date("Y-m-d",strtotime("+10 year"))."
";
?>
运行结果:
今天:2017-11-06
今天:2008-06-18
昨天:2017-11-05
明天:2017-11-07
一周后:2017-11-13
一周零两天四小时两秒后:2017-11-15 22:22:42
下个星期四:2017-11-09
上个周一:2017-10-30
一个月前:2017-10-06
一个月后:2017-12-06
十年后:2027-11-06
PHP 进阶的日期加减计算
<?php
// 默认时区
date_default_timezone_set(‘PRC‘);
echo "今天: ", date(‘Y-m-d H:i:s‘), "
"; // 输出当前时间
echo "明天: ", date(‘Y-m-d H:i:s‘, strtotime(‘+1 day‘)), "
"; // 输出明天时间
//strtotime 可以接受第二个参数,类型timestamp为指定日期
echo date(‘Y-m-d H:i:s‘, strtotime ("+1 day", strtotime(‘2017-11-11‘))), "
";
// 这里+1 day 可以修改参数1为任何想需要的数
// day也可以改成year(年)month(月)hour(小时)minute(分)second(秒)
echo date(‘Y-m-d H:i:s‘, strtotime("+1 day +1 hour +1 minute")), "
";
?>
运行结果:
今天: 2017-11-06 18:58:04
明天: 2017-11-07 18:58:04
2017-11-12 00:00:00
2017-11-07 19:59:04
PHP 高级的计算日期时间差
<?php
// 默认时区
date_default_timezone_set(‘PRC‘);
echo date("Y-m-d H:i:s"), "
";
// 日期天数相加函数
echo date(‘Y-m-d‘, strtotime(‘+1 day‘, strtotime(‘2016-09-12‘))), "
";
echo strtotime(‘2016-09-12‘), "
";
echo date("Y-m-d", ‘1473609600‘), "
";
echo date("Y-m-d", ‘1573609600‘), "
";
// 日期天数相加函数
$d = "2016-09-12 10:12:20";
echo date("Y-m-d", strtotime("$d +1 day")), "
";
// 把日期转换成时间截
function date2time($d){
$year=((int)substr("$d",0,4)); //取得年份
$month=((int)substr("$d",5,2)); //取得月份
$day=((int)substr("$d",8,2)); //取得几号
return mktime(0,0,0,$month,$day,$year);
}
echo date2time("2016-09-12"), "
";
$date_1="2066-09-12";
$date_2="2016-09-12";
$Date_List_a1=explode("-",$date_1);
$Date_List_a2=explode("-",$date_2);
$d1=mktime(0,0,0,$Date_List_a1[1],$Date_List_a1[2],$Date_List_a1[0]);
$d2=mktime(0,0,0,$Date_List_a2[1],$Date_List_a2[2],$Date_List_a2[0]);
$Days=round(($d1-$d2)/3600/24);
echo "$date_2 -> $date_1 相差: $Days 天", "
";
?>
运行结果:
2017-11-06 19:13:02
2016-09-13
1473609600
2016-09-12
2019-11-13
2016-09-13
1473609600
2066-09-12 -> 2016-09-12 相差: 18262 天
