I need to use the extension intl on my mac with XAMPP.

So I have followed this links:

Php-intl installation on XAMPP for Mac Lion 10.8

I restart always my apache server but isn't installed the extension. Because if I launch:

php -m | grep intl #should return 'intl'

return empty

The command that I can't launch without it is for composer and cakephp like this:

composer create-project --prefer-dist -s dev cakephp/app cakephp3

Return me this error:

Installing dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for cakephp/cakephp 3.0.*-dev -> satisfiable by cakephp/cakephp[3.0.x-dev].
    - cakephp/cakephp 3.0.x-dev requires ext-intl * -> the requested PHP extension intl is missing from your system.
  Problem 2
    - cakephp/cakephp 3.0.x-dev requires ext-intl * -> the requested PHP extension intl is missing from your system.
    - cakephp/bake dev-master requires cakephp/cakephp 3.0.x-dev -> satisfiable by cakephp/cakephp[3.0.x-dev].
    - Installation request for cakephp/bake dev-master -> satisfiable by cakephp/bake[dev-master].

So I need to solve the problem of ext-intl with the extension intl.

Can someone help me with this problem? How can I install this extension?




These below steps helped me, Just in case if you are using OSX

Steps from

  1. Check which php path is set i.e.

    root$: which php
  2. If you are using xampp on your mac it should be


    but if its


    you need to change your OSx php

    root$: PATH="/Applications/XAMPP/xamppfiles/bin:${PATH}" 
  3. Install icu4c

    root$: brew install icu4c 
  4. Install Intl via PECL

    root$: sudo pecl update-channels 
    root$: sudo pecl install intl 
  5. You can check if Intl was installed successfully

    root$: php -m | grep intl #should return 'intl' 




  • From extensions list in /Applications/XAMPP/xamppfiles/etc/php.ini file Add / Uncomment line. And restart Apache. Thanks @pazhyn

  • Before installing "intl" you have to install Autoconf if you have not installed it. Thanks @Digant

    • via Homebrew brew install autoconf automake or
    • by running below commands

      curl -OL
      tar xzf autoconf-latest.tar.gz
      cd autoconf-*
      ./configure --prefix=/usr/local
      sudo make install
      cd ..
      rm -r autoconf-*
