Install intl PHP extension OSX High Sierra

Question

How can I install intl PHP extension in PHP 7.1.7, which is delivered with osx high sierra?

Answer 1

In addition to what L. Grolleau says (run brew install php71-intl), paste the int.so path to the /php.ini at the end of the file:

extension=/usr/local/Cellar/php71-intl/7.1.11_20/intl.so
