What to do if the php date function is formatted incorrectly

The operating environment of this article: windows7 system, PHP7.1 version, DELL G3 computer

What to do if the php date function format error ? Date() function gets wrong time?

After getting the time through the date() function, you will find that 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 obtained. It 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 the ;date.timezone, 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");

The parameters are set as follows:

date_default_timezone_set(PRC) – set to Beijing time, PRC represents the People’s Republic of China

date_default_timezone_set('Asia /Shanghai') – set to Shanghai time, available in mainland China are also 'Chongqi' (Chongqing) and 'Urumqi' (Urumqi).

Available in Hong Kong and Taiwan: Asia/Macao, Asia/Hong_Kong, Asia/Taipei (Macau, Hong Kong, Taipei in order)

Singapore Region: Asia/Singapore (It seems that I haven’t seen Beijing)

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