How to set time zone in php.ini file?

How to set the time zone in the php.ini file: Open the php.ini file, search for "date.timezon" in the file; remove the ";" in front of ";date.timezone=", and add it here Fill in the corresponding time zone identifier after "=" in a sentence. For example, "PRC" can set the Chinese time zone.

Time is essential in life, and it is the same in PHP. Time sometimes needs to be stored to record something or displayed in the browser. .

In PHP, date and time are obtained through date and time functions. The date and time functions depend on the server's time setting. The server's time setting defaults to Greenwich Time (zero time zone time). If the time is not specifically set to a specific time zone, then the time obtained through the relevant PHP functions will be the zero time zone time. It is 8 hours less than Beijing time.

Division of time zones

The world is divided into 24 time zones. Each time zone has its own local time, and the local time in each time zone differs by 1 to 23 hours at the same time. For example, the local time in London, UK, and the local time in Beijing differ by 8 hours.

In the field of international radio communications, a unified time is used, called Universal Time Coordinated (UTC). UTC is the same as Greenwich Mean Time (GMT).

Due to the rewriting of the data() function in PHP5.0, the current date and time function is 8 hours less than the system time. The default setting of the PHP language is standard Greenwich Time (that is, the zero time zone is used), so to obtain the current local time, you must change the time zone setting in the PHP language.

Set the time zone in the php ini configuration file

The PHP configuration file is the php.ini file in the PHP installation directory. Find and open it. Then search for date.timezone in the file, we will see a piece of information as shown below:

[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
;date.timezone =

where;date.timezone =the preceding ;The function is the same as // in PHP. They both mean comments. Here we need to remove this ; and fill it in after = in this sentence. The corresponding time zone identifier is as follows:

[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone = Asia/Shangha

There are many time zone identifiers, which can be viewed by visiting "https://www.php.net/manual/zh/timezones.php", listed below Here are some commonly used time zone identifiers and their meanings:

Asia/Shanghai —— 上海
Asia/Chongqing —— 重庆
Asia/Urumqi —— 乌鲁木齐
Asia/Hong_Kong —— 香港
Asia/Macao —— 澳门
Asia/Taipei —— 台北
Asia/Singapore —— 新加坡
PRC —— 中国时区

Tip: In China, we can set the time zone to "Asia/Shanghai or PRC". Remember to restart the server after the setting is successful!

Example: The following is a piece of code to verify whether our settings are effective.

<?php
    echo date(&#39;Y-m-d H:i:s&#39;,time());
?>

The running result is as follows:

2020-07-21 11:45:20

If the running result is equal to the local time of our computer, it means that our setting is successful.
