You may already know about PHP timestamp, so how do we apply it to get the specific date? Today we will introduce to you the specific method of PHP Timestamp to obtain the current period.
Implementation function: Get the timestamp of a certain date, or get the PHP timestamp of a certain time.
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 by Timestamp , implement the required date and time.
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.
