PHP timestamp function summary and examples

echo strtotime(”2009-1-22″) Result: 1232553600

Description: Return the timestamp of 0:00:00 on January 22, 2009

Second, PHP timestamp function to obtain English text date and time Examples are as follows: For easy comparison, use date to convert the current timestamp and the specified timestamp into system time

(1) Print the timestamp at this time tomorrow strtotime(”+1 day”)

Current time: echo date(”Y-m-d H:i:s”,time()) Result: 2009-01-22 09:40:25
Specified time: echo date(”Y-m-d H:i: s",strtotime("+1 day")) Result: 2009-01-23 09:40:25

(2) Print the timestamp of yesterday at this time strtotime("-1 day")

Current time: echo date(”Y-m-d H:i:s”,time()) Result: 2009-01-22 09:40:25
Specified time: echo date(”Y-m-d H:i: s”,strtotime(”-1 day”)) Result: 2009-01-21 09:40:25

(3) Print the timestamp at this time next week strtotime(”+1 week ”)

Current time: echo date(”Y-m-d H:i:s”,time()) Result: 2009-01-22 09:40:25
Specified time: echo date(”Y-m-d H:i: s”,strtotime(”+1 week”)) Result: 2009-01-29 09:40:25

(4) Print the timestamp at this time last week strtotime(”-1 week ”)

Current time: echo date(”Y-m-d H:i:s”,time()) Result: 2009-01-22 09:40:25

(6) Print the timestamp of the specified day of the week strtotime("last Thursday")

Current time: echo date(”Y-m-d H:i:s”,time()) Result: 2009-01-22 09:40:25
Specified time: echo date(”Y-m-d H:i: s”,strtotime(”last Thursday”)) Result: 2009-01-15 00:00:00

As can be seen from the above PHP timestamp function example, strtotime can describe the date and time of any English text To parse it into a Unix timestamp, we use mktime() or date() to format the date and time to obtain the specified timestamp and achieve the required date and time. Example:

//Convert timestamp 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:$yearnmonth:$monthnday:$daynhour:$hoursnminutes:$minutesnseconds:$secondsn";

//Convert normal date to 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 it is an integer
*/
//You can format this
echo "time() displays year, month, day, hour, minute and second:" . date("Y-m-d H:i:s", time()) . "n";
// In this way, the hours, minutes and seconds are displayed together
echo "time() only displays the year, month and day:" . date("Y-m-d ", time()) . "n"; //Only the year is displayed.
echo "Timestamp Formatting: " . date("Y-m-d H:i:s", 1297845628) . "n"; //Use timestamp directly
