What should I do if the php acquisition time is wrong?

PHP gets the date and time incorrectly

Go straight to the topic, after getting the time through the date() function, you will find The hour time is wrong. It is 8 hours smaller than the current time. It is the same whether you use H or h. This is because the current time is Greenwich Mean Time, which is 8 hours different from Beijing time.

The solution is as follows:

1. Modify the php.ini configuration file

Open the php.ini file, usually in the php configuration root directory, find "date.timezone" in it, delete the preceding semicolon, and change it to date timezone = PRC. Save and restart the Apahce service (sometimes there will be problems with restart, just stop first and then start).

2. Add date_default_timezone_set(timezone_identifier) ​​function

This function means to set the current time zone, initialize the time, and add this sentence before the page header or get time statement.

For example:

date_default_timezone_set(PRC);
echo date("Y-m-d H-i-s");
Copy after login

The parameters are set as follows:

date_default_timezone_set(PRC) –设置为北京时间,PRC代表中华人民共和国
date_default_timezone_set(‘Asia/Shanghai’) –设置为上海时间,大陆可用的还有‘Chongqi’(重庆)、‘Urumqi’(乌鲁木齐)同样可以的
港台地区可用:Asia/Macao ,Asia/Hong_Kong ,Asia/Taipei (依次为澳门,香港,台北) 
新加坡地区:Asia/Singapore   (好像就是没看到北京的)
Copy after login

This function will always return True, but timezone_identifier must be entered, otherwise an error will be reported.

The following are all time zone identifiers: (for your reference)
