Install intl PHP extension OSX High Sierra - php

Question

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

Answer 1

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!

Answer 2

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.

Answer 3

open a terminal then type:
brew search intl
you should be able to see php71-intl, then run
brew install homebrew/php/php71-intl
then restart apache
sudo apachectl restart
then type:
php -i | grep intl
you should be able to see something like this:
Additional .ini files parsed => /usr/local/etc/php/7.1/conf.d/ext-intl.ini
intl
intl.default_locale => no value => no value
intl.error_level => 0 => 0
intl.use_exceptions => 0 => 0
Enjoy!

Answer 4

I'm running the brew 1.6.2, on OS High Sierra. The intl extension is not available in brew packages so far.
The #Mondy solution worked fine for me. After run the
curl -s http://php-osx.liip.ch/install.sh | bash -s 7.1
The packages will be available in /usr/local/php5 or /usr/local/php5-7.0.27-20180201-135220.
So in your /usr/local/etc/php/7.0/php.ini you can place the following lines to enable the intl extension:
[intl]
extension="/usr/local/php5/lib/php/extensions/no-debug-non-zts-20151012/intl.so"
In my case I prefered to create a file 'ext-intl.ini' in /usr/local/etc/php/7.0/conf.d/, just for a better organization.

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
This page has more info about port usage: https://guide.macports.org/chunked/using.html

Answer 6

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 7

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 8

I have managed to work this out.
First uninstall any php packages you have completely with brew, then run the brew update and brew doctor commands.
Now install with brew install php#7.1 (changed the version as needed) intl is included in the build for all php-formulae.
To confirm it is working run php -m | grep intl. You will see the intl extension is included. If not check the php.ini file and make sure the extension is being loaded.

Answer 9

Remove the following file with
rm /usr/local/etc/php/7.1/conf.d/ext-intl.ini
Worked for me, thanks to homebrew-core Issue

Answer 10

I installed php7.2 with brew and linked with that version on Mac, but cannot see even the version number 7.2 in phpinfo().
It always showed the last version(7.1) even though uninstall with brew, so the intl extension.
I found we have to modify httpd.conf file(in my case in /etc/apache2/httpd.conf), in that file you can find the
LoadModule php7_module libexec/apache2/libphp7.so
in that line you have to override with your new php72 path: in my case it was
LoadModule php7_module /usr/local/Cellar/php#7.2/7.2.31_1/lib/httpd/modules/libphp7.so
And restart apache, it works fine.

try this
brew install homebrew/php/php71-intl
