A summary of all PHP timestamp formats (getting time, timestamp), php

There are many kinds of functions in the PHP language, with different application methods and different functions. All the same. I hope it will be helpful for newbies to learn!

1. The PHP timestamp function obtains the unix timestamp of the specified date strtotime("2009-1-22"). The example is as follows:

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

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

2. The PHP timestamp function obtains the English text date and time. The example is as follows:

For comparison, use date to convert the current timestamp and the specified timestamp into system time

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

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

Specify 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

Specify 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

Specify 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

Specify time: echo date("Y-m-d H:i:s",strtotime("-1 week")) Result: 2009-01-15 09:40:25

(5) Print the timestamp of the specified day of the week strtotime("next Thursday")

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

Specify time: echo date("Y-m-d H:i:s",strtotime("next Thursday")) Result: 2009-01-29 00:00:00

(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

Specify time: echo date("Y-m-d H:i:s",strtotime("last Thursday")) Result: 2009-01-15 00:00:00

(7) Print the timestamp of zero o'clock the previous day

$ystd = strtotime('-1 day'); // The timestamp of yesterday’s moment
$ystd = date("Y-m-d", $ystd); // Yesterday's date d

$ystd = strtotime($ystd." 00:00:00"); // The timestamp of 24:00 yesterday morning

As can be seen from the above PHP timestamp function example, strtotime can parse the date and time description of any English text into a Unix timestamp. We combine the mktime() or date() formatted date and time to obtain the specified timestamp to achieve what is needed. Date time.

The above summary of all PHP timestamp formats (getting time, timestamp) is all the content shared by the editor. I hope it can give you a reference, and I hope everyone will support Bangkejia.
