Bug: CodeIgniter\I18n -> Class 'Locale' not found

[devorama]

Describe the bug
Was looking at this issue
#1807

when I tried to test his samples, I then looked at docs on how to load the class
https://codeigniter4.github.io/CodeIgniter4/libraries/time.html?highlight=settimezone
But instead I got the error
Class 'Locale' not found

Checked the source and there is nothing named Locale file or Text wise for a class

IncomingRequest has this logic in there code, but Time.php uses it directly

                        if (class_exists('\Locale', false))
			{
				\Locale::setDefault($locale);
			} 

A clear and concise description of what the bug is.

CodeIgniter 4 version
4.0.3

Affected module(s)
Time.php , part of CodeIgniter\I18n

Expected behavior, and steps to reproduce if appropriate
Should load the file

You need to have the intl extension installed on your machine.

For extra reference thanks to paulbalandan comment I found the php manual doc entry for it
https://www.php.net/manual/en/class.locale.php
one can get the install info etc from there based on the pacakge the class in part of.

You need to have the intl extension installed in your vhost PHP.

@huynhminhsangit you need to enable extension in php.ini for php-cli. There will be 2 php.ini files. You have to do in php-cli too.

Probably Location should be like this

/etc/php/8.0/cli/php.ini
/etc/php/8.1/cli/php.ini

[huynhminhsangit]

I try view in location you suggest but not see it

[kenjis]

You need to know where the php.ini locates. There may be many php.ini in your PC.
You can find the path with the phpinfo() function for web, or the php --ini command for CLI.
