Set the time zone in ci4 (CodeIgniter 4)

One 、 Origin

stay PHP In programming , We often need to get the current time , But in CodeIgniter4（ hereinafter referred to as CI4） The default time in is America/Chicago .

Then it will be very painful , Use the following code

echo date('Y-m-d H:i:s');

The output is （Chicago It's West 6 District ）

2022-01-11 21:06:25

But the actual East eighth district is

2022-01-12 11:06:25

Two 、 To solve the process

Surfing the Internet , Find two ways , I think they are all troublesome , But you can sum it up

Method 1

stay php.ini Find data.timezone= Remove the one in front of it ; Number , Then set the data.timezone= “Asia/Shanghai”.

Method 2

In use date() Add a line before the function

date_default_timezone_set("Asia/Shanghai");

3、 ... and 、 Personally, I feel that CI4 A better way

The two methods mentioned above , I feel a little troublesome ,

Method 1 if you forget when configuring a new environment , The data output or stored in the database will be ruined .

In method 2, add the line before use , It is troublesome to write code .

But in CI4 in , Can be in .env Add a line to the file , It can be solved

app.appTimezone = "Asia/Shanghai"

Four 、 At the end

CI4 This frame and PHP I don't know much , But a search came down about CI4 There are still few articles , Even there is no introduction to the time zone , So I plan to write this article to give future students less detours when they encounter this problem , We make progress together .
