strtotime()函数的作用是将日期时间描述解析为 Unix 时间戳

int?strtotime?( string time [, int now] )

?>

本函数预期接受一个包含美国英语日期格式的字符串并尝试将其解析为 Unix 时间戳(自 January 1 1970 00:00:00 GMT 起的秒数),其值相对于?now?参数给出的时间,如果没有提供此参数则用系统当前时间。

-------------------------------

?

在PHP里得到前天和昨天的日期的代码
前天去面试的时候也是这样,不过我当时记不起来了.就记得MYSQL里面的date_sub(now(),'interval 1 day');date('Y/m/d h:i:s',mktime(date('h'), date('i'), date('s'), date('m') , date('d')+1, date('Y')));

--------------------------------------------?
先得到今天的UNIXTIME?
然后减去一天或两天的秒数?
把减后的UNIXTIME格式化成日期。?
--------------------------------------------

以下为引用的内容:
date_default_timezone_set('Asia/Shanghai');?
#昨天?
echo date("Y/m/d h:i:s",time()-24*60*60);?
echo "
";?
#前天?
echo date("Y/m/d h:i:s",time()-2*24*60*60);?
?>?

--------------------------------------------?
up?
--------------------------------------------?
方法有很多种啊, 我也介绍一种吧:?
date("Y/m/d H:i:s", strtotime("1 days ago"));?
date("Y/m/d H:i:s", strtotime("2 days ago"));?
--------------------------------------------?
date("Y/m/d H:i:s",mktime(0,0,0,date("m"),date("d")-1,date("Y")));?
--------------------------------------------?
以前算时间总是很烦人,呵呵,学了了下,下面是下个星期现在的时间。?
date_default_timezone_set('Asia/Shanghai');?
$tmp = time()+60*60*24*7;?
print date("m/d/Y H:i:s", $tmp);?
--------------------------------------------?
再加一个:?
$time_yes=localtime(time()-24*60*60, true);?
$time_b_yes=localtime(time()-2*24*60*60, true);?
$yesterday=$time_yes['tm_mday'];?
$the_day_before_yes=$time_b_yes['tm_mday'];?
--------------------------------------------?
time()-86400 昨天的

以下为引用的内容:

?
//昨天?
print date('Y-m-d' , strtotime('-1 day'));?
//上星期?
print date('Y-m-d' , strtotime('-1 week'));?
//上个月?
print date('Y-m-d' , strtotime('-1 month'));?
//去年?
print date('Y-m-d' , strtotime('-1 year'));?
?>


--------------------------------------------

strtotime得到一个时间戳, 然后你自己格式化.?
strtotime('yesterday');?
strtotime('-2 day');

Introduction to methods and usage of using Date and SimpleDateFormat classes to process time in Java Introduction to methods and usage of using Date and SimpleDateFormat classes to process time in Java Apr 21, 2023 pm 03:01 PM

1. Introduction The Date class in the java.util package represents a specific time, accurate to milliseconds. If we want to use our Date class, then we must introduce our Date class. Writing the year directly into the Date class will not produce the correct result. Because Date in Java is calculated from 1900, so as long as you fill in the first parameter with the number of years since 1900, you will get the year you want. The month needs to be subtracted by 1, and the day can be inserted directly. This method is rarely used, and the second method is commonly used. This method is to convert a string that conforms to a specific format, such as yyyy-MM-dd, into Date type data. First, define an object of Date type Date
