What should I do if the php acquisition time is not correct? ?

PHP getting the date and time is wrong

Go straight to the topic. 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. No matter you use H, it’s the same whether you use h. This is because the current value 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" in it, and delete the previous one semicolon and change 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 People's Republic of China
date_default_timezone_set('Asia/Shanghai') – Set to Shanghai time, available in mainland China are also 'Chongqi' (Chongqing), 'Urumqi' (Urumqi) and Hong Kong and Taiwan regions. Available: Asia/Macao, Asia/Hong_Kong, Asia/Taipei (Macau, Hong Kong, Taipei in order)

This function will always Return True, but be sure to enter timezone_identifier, otherwise an error will be reported.
