There are many kinds of functions in the PHP language, different application methods, the implementation of the function is not the same. Hope to be helpful to the Novice's study!
First, the PHP timestamp function gets the UNIX timestamp strtotime ("2009-1-22″" example) of the specified date as follows:
Echo strtotime ("2009-1-22″") Result: 1232553600
Note: Return January 22, 2009 0:0 0 seconds time stamp
Second, the PHP timestamp function gets the English text date time example as follows:
Easy to compare, using date to convert the timestamp to the system time with the specified timestamp
(1) Print tomorrow at this time the timestamp strtotime ("+1 Day")
Current Time: Echo Date ("Y-m-d h:i:s", Time ()) Result: 2009-01-22 09:40:25
Specified time: echo date ("Y-m-d h:i:s", Strtotime ("+1 Day") Results: 2009-01-23 09:40:25
(2) Print the timestamp strtotime ("-1 day") at this time yesterday
Current Time: Echo Date ("Y-m-d h:i:s", Time ()) Result: 2009-01-22 09:40:25
Specified time: echo date ("Y-m-d h:i:s", Strtotime ("1 day")) Results: 2009-01-21 09:40:25
(3) Print the timestamp strtotime ("+1 Week") at this time next week
Current Time: Echo Date ("Y-m-d h:i:s", Time ()) Result: 2009-01-22 09:40:25
Specified time: echo date ("Y-m-d h:i:s", Strtotime ("+1 Week") Results: 2009-01-29 09:40:25
(4) Print the timestamp strtotime ("-1 week") at this time last week
Current Time: Echo Date ("Y-m-d h:i:s", Time ()) Result: 2009-01-22 09:40:25
Specified time: echo date ("Y-m-d h:i:s", Strtotime ("1 week")) Results: 2009-01-15 09:40:25
(5) Print a timestamp strtotime ("next Thursday") that specifies the next day of the week
Current Time: Echo Date ("Y-m-d h:i:s", Time ()) Result: 2009-01-22 09:40:25
Specified time: echo date ("Y-m-d h:i:s", Strtotime ("next Thursday") Results: 2009-01-29 00:00:00
(6) Print a timestamp strtotime ("last Thursday") that specifies the previous week
Current Time: Echo Date ("Y-m-d h:i:s", Time ()) Result: 2009-01-22 09:40:25
Specified time: echo date ("Y-m-d h:i:s", Strtotime ("last Thursday") Results: 2009-01-15 00:00:00
(7) Print the timestamp of 0 points the day before
$YSTD = Strtotime ('-1 day '); The time stamp of the moment yesterday
$YSTD = Date ("y-m-d", $YSTD); Yesterday's Date D
$YSTD = Strtotime ($ystd.) 00:00:00 "); Yesterday 24 o'clock in the morning the whole time stamp
The above PHP Timestamp function example shows that strtotime can resolve the date-time description of any English text to a Unix timestamp, and we combine the mktime () or date () format date time to get the specified timestamp to achieve the required date time.
The above PHP timestamp format all summary (get time, time stamp) is small to share all the content of everyone, hope to give you a reference, but also hope that we support cloud habitat community.
