PHP Date and Time functions

1. Time zone settings

Method One: Set the Date.timezone=asia/hong_kong of the php.ini, so that the system default time is East 8 zone

Method Two: Use the function Date_default_timezone_set () to set the time zone to Date_default_timezone_set ("Asia/hong_kong")

2. Get the current timestamp

Use the time () function to return the current time and date directly, and the timestamp represents the number of seconds from January 1, 1970 0:0 0 seconds to the time of the program's Run

3. Get the current date and time

Use the date () function to return the current date. Date () has many parameters, such as using "D" to return the date of the current month 01 to 31

4. Resolve date and time to UNIX timestamp

Use the Maketime () function to generate the appropriate UNIX timestamp


Let's look at an example:
<?php

Date_default_timezone_set ("Asia/hong_kong");

$timefuture = Mktime (0,0,0,01,01,2016);
$timenow = time ();
$timecount = $timefuture-$timenow;
$day = Round ($timecount/86400);

echo Date ("Current time: Y year M D Day [L]h point I min s second", $timenow). " <br> ";
echo "is also available from January 1, 2016". $day. " Days. "." <br> ";


?>

The result of the operation is:
