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

I find a solution.

curl -s http://php-osx.liip.ch/install.sh | bash -s 7.1

Then I copied intl.so from the installation to my extension directory, which is defined into my php.ini.

Answer 2

try this

brew install homebrew/php/php71-intl

Answer 3

try this on Mac

php -v
sudo port install php7*-intl

More information

You can find port packages by this page https://www.macports.org/ports.php?by=name&substr=intl

And you can install port through these steps: https://guide.macports.org/chunked/installing.macports.html

curl -O https://distfiles.macports.org/MacPorts/MacPorts-2.5.4.tar.bz2
tar xf MacPorts-2.5.4.tar.bz2
cd MacPorts-2.5.4/
./configure
make
sudo make install

And change ~/.bash_profile

export PATH=/opt/local/bin:/opt/local/sbin:$PATH

If there is error, check following steps:

check port

sudo port list
sudo port selfupdate
sudo port search --name --glob 'php*'
sudo port install php**-intl

Answer 4

So I had the exact same issue. As noted by other folks commenting here, High Sierra comes with PHP 7.1 installed and this PHP version has intl compiled with it

In my case, I followed part of Neodork comment's in the following Valet+ issue:

"Install" PHP 7.1 (so it comes from brew itself, not the one installed by High Sierra)

brew install php@7.1

Upgrade it to latest version

brew upgrade php@7.1

Symlinks for references in Cellar:

brew link --overwrite --force php@7.1

Change PHP path in my bash profile

echo 'export PATH="/usr/local/opt/php@7.1/bin:$PATH"' >> ~/.bash_profile
echo 'export PATH="/usr/local/opt/php@7.1/sbin:$PATH"' >> ~/.bash_profile

Reload your bash profile (you can close the terminal and open it again)

. ~/.bash_profile

Check for Intl

php -m | grep intl

Note: If you come across with warnings like:

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/opt/php71-intl/intl.so'

Then you have to disable the previous intl:

mv /usr/local/etc/php/7.1/conf.d/ext-intl.ini /usr/local/etc/php/7.1/conf.d/ext-intl.ini.disabled

Hope it helps!

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

Answer 6

After the integration from brew/php to brew/core, the intl extension is included by the default installation. I also had the same problem the intl extension wasn't working. The problem I had was the command-line environment was not using the installed version of PHP but the default version from macOS system.

To enable the installed version, you need to do this:

After brew install php@7.1

You need to link the installed PHP version by brew link php@7.1

Then you need to OPEN A NEW TERMINAL to make it effective.
Then double check the PHP binary path, which php

make sure it's /usr/local/bin/php instead of /usr/bin/php

Then check if the intl extension is enabled, php -m | grep intl

It works for me.
