Reason: Network resource organization
Since php5.1.0, the option date.timezone has been added to php.ini, and it is turned off by default, that is, the displayed time (no matter what php command is used) is Greenwich Mean Time and our time (Beijing time). ) by exactly 8 hours.
The available values for timezone in mainland China are: Asia/Chongqing, Asia/Shanghai, Asia/Urumqi, PRC (Chongqing, Shanghai, Urumqi, the People's Republic of China in turn) available in Hong Kong and Taiwan: Asia/Macao, Asia/Hong_Kong, Asia/ Taipei (in order of Macau, Hong Kong, Taipei) and Singapore: Asia/Singapore Others: Etc/GMT-8, Singapore, Hongkong
Solution one:
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 line ";date.timezone=" in php.ini, remove the ";", change it to "date.timezone = PRC" (PRC: People's Republic of China), restart Apache, the problem is solved.
