strtotime parses the date and time description of any English text into Unixtimestamp[converts system time into unixtimestamp]

1. Get the unix timestamp of the specified date strtotime("2009-1-22〃). The example is as follows:
echo strtotime("2009-1-22" ) Result: 1232553600
Description: Returns 0:00:00 on January 22, 2009Timestamp

Second, the example of obtaining the English text date and time is as follows:
is convenient for comparison. Use date to convert the current timestamp and the specified timestamp into the system Time

(1) Print the timestamp at this time tomorrow strtotime("+1 day")
current time : echo date("Y-m-d H:i:s" ,time()) Result: 2009-01-22 09:40:25
Specify time: echo date(”Y-m-d H:i:s”,strtotime(”+1 day”)) Result: 2009-01- 23 09:40:25

(2) Print the PHP timestamp at this time yesterdaystrtotime("-1 day")
Current time: echo date("Y-m-d H:i:s ”,time()) Result: 2009-01-22 09:40:25
Specify time: echo date(”Y-m-d H:i:s”,strtotime(”-1 day”)) Result: 2009-01 -21 09:40:25

(3) Print the timestamp at this time next week strtotime("+1 week")
current time : echo date("Y-m-d H:i: s”,time()) Result: 2009-01-22 09:40:25
Specify time: echo date(”Y-m-d H:i:s”,strtotime(”+1 week”)) Result: 2009- 01-29 09:40:25

(4) Print the timestamp at this time last week strtotime(”-1 week“)
current time : echo date(”Y-m-d H:i: s”,time()) Result: 2009-01-22 09:40:25
Specify time: echo date(”Y-m-d H:i:s”,strtotime(”-1 week”)) Result: 2009- 01-15 09:40:25

(5) Print the PHP timestamp of the specified day of the weekstrtotime("next Thursday")
current time: echo date("Y-m-d H:i:s ”,time()) Result: 2009-01-22 09:40:25
Specify time: echo date(”Y-m-d H:i:s”,strtotime(”next Thursday”)) Result: 2009-01- 29 00:00:00

(6) Print the timestamp of the specified day of the week strtotime("last Thursday")
current time : echo date("Y-m-d H:i:s" ,time()) Result: 2009-01-22 09:40:25
Specify time: echo date(”Y-m-d H:i:s”,strtotime(”last Thursday”)) Result: 2009-01-15 00:00:00

As can be seen from the above example, strtotime can parse the date and time description of any English text into Unix timestamp . We combine mktime() or date() to format the date time to obtain the specified The PHP Timestamp implements the required date and time.
