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
Two, php timestamp function get the English text date time example is 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:
<?php
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";
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
Turn the normal date into a timestamp, and if it is sometimes the same in seconds,
$year = ((int) substr ("2008-12-04", 0,4));//year acquired
$month = ((int) substr ("2008-12-04", 5,2));//Get month
$day = ((int) substr ("2008-12-04", 8,2));//Date
Echo mktime (0,0,0, $month, $day, $year);
?>
parts to be aware of
< a >, PHP time large to divide into two, one is the timestamp type (1228348800), and the second is the normal date format (2008-12-4)
< two >, php5.1 above time stamp and actual time difference 8 hours, the solution is as follows
1, the simplest way is not to use php5.1 above version-obviously this is undesirable Method!!!
2, modify the php.ini. Open php.ini Find Date.timezone Remove the preceding semicolon = add Asia/shanghai After, restart Apache server can--the disadvantage is that if the program
Put on someone else's server, can not modify the php.ini, that will not be.
3, in the program to add time to initialize the statement that is: "Date_default_timezone_set (" Asia/shanghai "); "This can be arbitrarily set by the programmer, my push
Kanzian
Time zone identifiers, the values available in mainland China are: prc,asia/chongqing, Asia/shanghai, Asia/urumqi (Chinese, Chongqing, Shanghai, Urumqi, respectively), Etc/gmt-8,asia/harbin
Taiwan available: Asia/macao, Asia/hong_kong, Asia/taipei (Macau, Hong Kong, Taipei, respectively)
and Singapore: Asia/singapore
It's time for the output to be in Beijing.
