Date Posted: 05-02-2018

In this post, we will explain how to install mcrypt for php  on mac os high sierra for a Development Server.

Step 1:  Search the package:

brew search mcrypt

Result:

==> Searching local taps... homebrew/php/php71-mcrypt mcrypt homebrew/php/php53-mcrypt
homebrew/php/php54-mcrypt homebrew/php/php55-mcrypt homebrew/php/php56-mcrypt homebrew/php/php70-mcrypt libtomcrypt

Step 2: Search my php version to know what can I need to install:

php --version

Result:

PHP 7.1.7 (cli) (built: Jul 15 2017 18:08:09) ( NTS ) Copyright (c) 1997-2017 The PHP Group Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies

Step 3: Install the correct package, for me was 7.1.7 => homebrew/php/php71-mcrypt

brew install homebrew/php/php71-mcrypt

Step 4: Find the find “mcrypt.so” extension file

find /usr/ -type f -name "mcrypt.so"

Result:

find: /usr//local/Cellar/php71-mcrypt/7.1.13_19/mcrypt.so

Step 5: Search the php.ini

php -i | grep 'Configuration File'

Result (if exist):

Configuration File (php.ini) Path => /etc Loaded Configuration File => /etc/php.ini

Step 6: Add the next line at the end on /etc/php.ini (see the last step your correct path) the extension mcrypt.so

extension=/usr/local/Cellar/php71-mcrypt/7.1.13_19/mcrypt.so

If there is no php.ini file,  then you need to make one from php.ini.default in the same location like so: If the php.ini does not exist in etc folder please follow below steps.

sudo cp /etc/php.ini.default /etc/php.ini

Step 7: And allow write capability

sudo chmod u+w  /etc/php.ini

Step 8: Please find the mcrypt.so path and add into php.ini file

Configuration File (php.ini) Path => /etc Loaded Configuration File => /etc/php.ini

Step 9: Restart the apachectl

That’s it, create a php page with the function phpinfo();  to see if it loaded correctly.
