Strtotime function

The function resolves the datetime description of any English text to a Unix timestamp.

One, the PHP timestamp function gets the UNIX timestamp for the specified date

Examples are as follows:

Echo strtotime ("2009-1-22″) Results: 1232553600

Description: Return January 22, 2009 0:0 0 seconds timestamp

Second, PHP timestamp function get English text date time

Examples are as follows:

Easy to compare, use date to convert time stamp to system time with specified timestamp

(1) Print the timestamp for tomorrow at this time Strtotime ("+1 Day")

Current Time: Echo Date ("Y-m-d h:i:s," time ()) Results: 2009-01-22 09:40:25

Time Specified: Echo date ("Y-m-d h:i:s", Strtotime ("+1 Day") Results: 2009-01-23 09:40:25

(2) Print the timestamp at this time yesterday Strtotime ("-1 day")

Current Time: Echo Date ("Y-m-d h:i:s," time ()) Results: 2009-01-22 09:40:25

Time Specified: Echo date ("Y-m-d h:i:s", Strtotime ("1 day") Results: 2009-01-21 09:40:25

(3) Print timestamp strtotime ("+1 Week") at this time next week

Current Time: Echo Date ("Y-m-d h:i:s," time ()) Results: 2009-01-22 09:40:25

Time Specified: Echo date ("Y-m-d h:i:s", Strtotime ("+1 Week") Results: 2009-01-29 09:40:25

(4) Print timestamp strtotime ("1 week") at this time last week

Current Time: Echo Date ("Y-m-d h:i:s," time ()) Results: 2009-01-22 09:40:25

Time Specified: Echo date ("Y-m-d h:i:s", Strtotime ("1 Week") Results: 2009-01-15 09:40:25

(5) Print the time stamp specified next week strtotime ("next Thursday")

Current Time: Echo Date ("Y-m-d h:i:s," time ()) Results: 2009-01-22 09:40:25

Time Specified: Echo date ("Y-m-d h:i:s", Strtotime ("next Thursday") Results: 2009-01-29 00:00:00

(6) Print the timestamp strtotime ("last Thursday") specified on the previous day of the week

Current Time: Echo Date ("Y-m-d h:i:s," time ()) Results: 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

The PHP timestamp Function example above shows that Strtotime can parse the datetime description of any English text into a Unix timestamp, and we get the specified timestamp by combining mktime () or date () format date time to achieve the required date time.
