In a Nutshell we just need to do get the full binary package of PHP and install it on OSX, this version comes with intl.so, and we will copy it out of its install directory and drop it into our PHP version.
Get & Install the Binary Package
This website provides the packages so we just pick the version we want to use and run their install script: https://php-osx.liip.ch/
curl -s http://php-osx.liip.ch/install.sh | bash -s 5.6
This would install php 5.6 and we we can copy the intl.so file out of the install directory and drop it in our PHP folder.
cp /usr/local/php5-5.6.31-20170817-164511/lib/php/extensions/no-debug-non-zts-20131226/intl.so /Applications/MAMP/bin/php/php5.6.31/lib/php/extensions/no-debug-non-zts-20131226
In this example I am using Mamp so I should drop it into the extensions/no-debug-non-zts-20131226 folder of my PHP version. These are the same version of PHP so the path should be the same, its just that Mamp holds its PHP binary files in the MAMP app.
cp /usr/local/php5-7.3.8-20190811-205217/lib/php/extensions/no-debug-non-zts-20180731/intl.so /Applications/MAMP/bin/php/php7.3.8/lib/php/extensions/no-debug-non-zts-20180731/
Enable the extension
Find the php.ini file for the version of php you want to use in my case I was using php5.6.31 (you can tell from copy/paste terminal line), and under “Extensions” add the line:
And restart Mamp, and your extension should now be installed!
Set PHP version for Terminal – Required for CakePHP / Composer based installs
Frustratingly, terminal often runs a different version of PHP when installing with composer, so for example, CakePHP refuses to install because its running a version of PHP that doesn’t have intl.so. installed. Check your version of PHP in terminal by typing:
if it is a different version that the one you want, set the correct one by using an alias in your .bashrc file.
sudo nano ~/.bashrc
Add the line (Replace php path with your path):
Then finally reload your bashrc file with:
