PHP timestamp and date conversion _php Tutorial

You may have some knowledge of PHP timestamps, so how do we apply it to get a specific date? Let us introduce you to the specific ways PHP timestamps get the current period.

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

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 datetime to achieve the required date time.

Strtotime to parse the datetime description of any English text into a UNIX timestamp [convert system time to 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 PHP timestamp strtotime ("-1 day") at this time yesterday
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 PHP timestamp strtotime ("next Thursday") that specifies the next day of the 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 ("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 PHP timestamp by combining mktime () or date () format date time to achieve the required date time.
