does a php 7.3 cassandra driver exist? I have php 7.3 on Debian 10. I'm trying to get the Apache Cassandra driver for php 7.3.

The one provided by datastax (https://github.com/datastax/php-driver) only works up to 7.1, and the pecl one (pecl install cassandra) also only work up to PHP 7.1.x. Does one for 7.3 exist? I have searched around and can't find it.
PHP &amp; Ruby drivers are put on hold - they will receive only critical bug fixes but not the new functionality. You should be able to compile existing code for PHP versions beyond 7.1, but DataStax doesn't provide pre-built versions.
