There are many kinds of functions in the PHP language, different ways of application, and the functions of implementation are not the same. In this paper, we summarize the PHP timestamp function, hoping to be a reference learning object.

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

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.

Example:

Time Stamp to date
$date _time_array = getdate (1297845628); 1311177600 1316865566
$hours = $date _time_array["Hours"];
$minutes = $date _time_array["Minutes"];
$seconds = $date _time_array["seconds"];
$month = $date _time_array["Mon"];
$day = $date _time_array["Mday"];
$year = $date _time_array["year"];

echo "Year: $year \nmonth: $month \nday: $day \nhour: $hours \nminutes: $minutes \nseconds: $seconds \ n";

Normal date turn timestamp
Echo mktime (0, 0, 0, 9, 18, 2011). "\ n";
Echo mktime (0, 0, 0, 9, 25, 2011). "\ n";

/*
Time ();
is to get the current time, but to get an integer type
*/
This can be formatted
echo "Time () displays the day of the month and seconds:". Date ("Y-m-d h:i:s", Time ()). "\ n";
So even when the seconds show together
echo "Time () displays only month Day:". Date ("Y-m-d", Time ()). " \ n "; Year-only date

echo "timestamp format:". Date ("Y-m-d h:i:s", 1297845628). "\ n"; Using timestamps directly

/* Vim:set ts=4 sw=4 sts=4 tw=100 noet: */
