  Thread Safety => disabled
Download an archive for an appropriate version of the module from the PECL website: https://pecl.php.net/packages.php
Unpack the archive anв сopy the php_<modname>.dll and php_<modname>.pdb files from it to %plesk_dir%Additional\PleskPHP71\ext.
Open the file %plesk_dir%\Additional\PleskPHP71\php.ini in a text editor.
Add the following line in the file under "Dynamic Extensions" section:

CONFIG_TEXT: extension=php_<modname>.dll

Note: Some modules may require additional files. Please refer to their documentation for details.
