How to enable the intl extension to use CakePHP or Magento on mac

Introduction

When you first install CakePHP3 or Magento, I guess “enable the intl extension” is the first hurdle.
It’s been a while since I first dealt with this problem, but I remember it was complicated a little.

Today, I’m going to introduce some solutions that worked for me.

The Terminal command might intimidate you, but don’t worry!
I’m going to share every step I took.

Environment

macOS Catalina
MAMP 5.7
CakePHP3 / Magento

Let’s get started!

Step1: Open Terminal and Check if Homebrew is installed

Users-MacBook:~ user$ which brew

If it returns:
/usr/local/bin/brew → Step3
not found → Step2

Step2: Install Homebrew

Access to https://brew.sh/, then copy and Paste an install command.Users-MacBook:~ user$ Copy & Paste Here

Step3: Check PHP path

Users-MacBook:~ user$ which php

If it returns:
/usr/bin/php → Step4
/Applications/MAMP/bin/php/php7.2.7/bin → Step5

Step4: Change Path

Users-MacBook:~ user$ PATH=”/Applications/MAMP/bin/php/php7.2.7/bin:${PATH}”

Step5: Install icu4c

Users-MacBook:~ user$ brew install icu4c

Step6: Install intl

Users-MacBook:~ user$ sudo pecl update-channels
Users-MacBook:~ user$ sudo pecl install intl

If you get “Cannot find autoconf” message:Users-MacBook:~ user$ brew install autoconf

Succeed → Step7
Failed → Skip Step7

Step7: Activate intl & Restart XAMPP

Open /Applications/MAMP/bin/php/php7.2.7/conf/php.ini , and find extension=intl.so;extension=intl.so

extension=intl.so   // Remove semicolon

Then, restart MAPP.

STEP8: Check the installation

There are two ways to check if our intl installation is success. First is using the following command

$ php -m | grep intl
