如何在macOS Mojave上启用PHP Intl扩展？

Question

I'm trying to install Magento (2.3.0) on macOS Mojave. Magento shows PHP Extension intl. is missing.

I tried the below to resolve:

1. Made a copy of php.ini using cp /etc/php.ini.default php.ini
2. Removed ";" before extension=php_intl.dll
3. Restart Apache sudo apachectl restart

But the above did not resolve.

On checking php -v, i'm seeing the below error:

PHP Warning:  PHP Startup: Unable to load dynamic library 
'/usr/lib/php/extensions/no-debug-non-zts-20160303/php_intl.dll' - 
dlopen(/usr/lib/php/extensions/no-debug-non-zts-20160303/php_intl.dll, 
0x0009): dlopen(): file not found: /usr/lib/php/extensions/no-debug- 
non-zts-20160303/php_intl.dll in Unknown on line 0
PHP 7.1.19 (cli) (built: Aug 17 2018 20:10:18) ( NTS )
Copyright (c) 1997-2018 The PHP Group

There are only 2 files under /usr/lib/php/extensions/no-debug-non-zts-20160303 namely opache.so and xdebug.so

How can i install or enable "PHP Extension intl" on my macOS Mojave?

Answer 1

Here's a solution that worked for me:

1. Find all PHP versions installed brew list | grep php
2. Remove all versions of PHP brew remove --ignore-dependencies --force php70 php71 php72 (based on what you see above)
3. Install PHP brew install php72 (i chose 7.2, 7.3 is not supported yet by several vendors)
4. Run the command which php should show you the path to the installed PHP. Copy the path.
5. Update your bash_profile vi ~/.bash_profile and add this line to the file: export PATH=/usr/local/php5/bin:$PATH
6. Save and run this source ~/.bash_profile
7. Check if PHP Intl Extension is installed using php -m | grep intl. If the installation went well, we will see intl listed. If not the extension is not installed.

I think from PHP 7 (not sure of the version), the extensions are available by default and we need not enable them in php.ini file explicitly.
