PHP timestamp format rollup (get time, timestamp), php_php tutorial

PHP timestamp Format all summary (get time, timestamp), PHP

There are many kinds of functions in the PHP language, different ways of application, and the functions of implementation are not the same. Hope to learn from the novice to help!

One, the PHP timestamp function gets the UNIX timestamp of 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, the PHP timestamp function obtains the English text date time example 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

(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 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.

The above PHP timestamp format all summarized (get time, time stamp) is a small part of the whole content to share to everyone, I hope to give you a reference, but also hope that we have a lot of support to help guests home.
