Starting from php5.1.0, the date.timezone option has been added to php.ini, and by default The following is closed, which means that the displayed time (no matter what php command is used) is exactly 8 hours different from Greenwich Mean Time and our time (Beijing time).

Solution 1:

Insert before adding the time: CODE: (It seems that there is no need to add) date_default_timezone_set(PRC);

Solution two:

echo date("Y-m-d H:i:s", time()+8*60*60);

Solution three (modify the php.ini file):

Find the ";date.timezone=" line in php.ini, remove the ";" and change it to "date.timezone = PRC" (PRC: People's Republic of China People's Republic of China). Restart Apache and the problem is solved. .
