admin You can compile an extension (usually is: phpize + ./configure + (g)make), run your own php-fpm/php-cgi instantiation and use it with your domain: https://docs.serv00.com/CGI/#fastcgi-configuration The easier way is to load an existing extension: https://docs.serv00.com/PHP/#loading-additional-php-modules If the extension you need is missing we can install it globally. PHP configuration you can change by .user.ini file: https://docs.serv00.com/PHP/#php-configuration
zhangwanli admin I am referring to the compiled third-party .so file, but when I upload the file, it seems that the permissions are not enough
admin zhangwanli You can use your own .so files (no matter whether compiled locally or not) only with your own PHP instance - it's a PHP limitation.
