PHP Strtotime function Specific application method _php tutorial

In the following article we will give you a detailed description of the PHP strtotime function related usage. This function for beginners is still unfamiliar, I hope that the content described in this article can help us improve the

Implementation: Gets the timestamp of a date, or gets the timestamp of a time.

The PHP strtotime function parses the datetime description of any English text into a UNIX timestamp [converts the system time to a UNIX timestamp]

One, the Unix timestamp for the specified date strtotime ("2009-1-22″") example is as follows:

Echo strtotime ("2009-1-22") Results: 1232553600
Description: Return January 22, 2009 0:0 0 seconds timestamp

Second, get the English text date and 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 above example 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.

These are the specific concepts of PHP strtotime functions.
