Install a PHP extension using PECL

Use the following guideline to compile your own extensions. This example uses the mongodb extension and PHP 7.0.15. You can find more PHP extensions here.

1. Check the “Make this version available on the command line” check box on your Languages > PHP tab.
2. Restart your servers. A PECL alias now exists in your “~/.profile” file.
3. Open Terminal.app (/Applications/Utilities) change the directory to /Applications/MAMP/bin/php/php[Version]/bin and enter the following line into the terminal and hit enter:
   pecl install mongodb Your extension should now build and you should see the following result.
4. A mongodb.so extension should now be in your “/Applications/MAMP/bin/php/php7.0.15/lib/php/extension/no-debug-non-zts” folder.
5. Go to File > Edit Templates > PHP > PHP7.0.15 and add extension=mongodb.so.
6. Restart your servers and verify the extension has been loaded by checking phpInfo.
