To support the expanded use of Websockets for additional dynamic pages within the Submitty website, we must remove a restriction on a specific php function.

Version v20.08.00 requires the following edits:

1. Locate your php.ini file.

   It is probably something like /etc/php/7.2/fpm/php.ini.

   Note: You can run this command to print your specific version of php:

   php -r 'print PHP_MAJOR_VERSION.".".PHP_MINOR_VERSION."\n";'
   

2. Edit this file:
   Remove stream_socket_client from the list of disabled_functions.
   Save the file.

3. Restart php fpm:

   sudo systemctl restart php7.2-fpm
   

   Or more generally:

   sudo systemctl restart php$(php -r 'print PHP_MAJOR_VERSION.".".PHP_MINOR_VERSION;')-fpm
