What is the error when connecting PHP intl extension?

Question

PHP

I was working for myself, and suddenly Yii gives me

Message format 'date' is not supported. You have to install PHP intl extension to use this feature.

I hate everything that has to do with installing packages. I just don't understand what's what.
The first result of googling said: just uncomment the line in php.ini and change the path to php (I have XAMPP).
No sooner said than done:
PATH="/Applications/XAMPP/xamppfiles/bin:${PATH}"
;extension=php_intl.dll => extension=php_intl.dll
No result. What to do

Answer 1

I'm not good at windows, but it seems like in the directory with php.exe there should be an ext directory, in which php_intl.dll should actually be. If not, then you need to find and put it. If you didn't restart the web server after you uncommented the line, restart it.
