How to install a PECL module in PHP provided by Plesk on Windows Server?

Answer

Warning: The configuration is not officially supported. All instructions below should be done at your own risk.

1. Connect to a Plesk server via RDP.

2. Start a command prompt as an Administrator.

3. Determine architecture and thread safety of a PHP version. Below is an example for PHP 7.3:

   • Architecture

     C:\> "%plesk_dir%\Additional\PleskPHP73\php.exe" -i | findstr "Architecture"
     Architecture => x64

   • Thread-safety

     C:\> "%plesk_dir%\Additional\PleskPHP73\php.exe" -i | findstr "Thread Safety"
     Thread Safety => disabled

4. Download an archive for an appropriate version of the module from the PECL website: https://pecl.php.net/packages.php

5. Unpack the archive anв сopy the php_<modname>.dll and php_<modname>.pdb files from it to %plesk_dir%Additional\PleskPHP71\ext.

6. Open the file %plesk_dir%\Additional\PleskPHP71\php.ini in a text editor.

7. 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.

8. Restart IIS to apply the changes with the command:

   C:\> iisreset
