As of this PR phpredis is the new default client for Laravel v6.0 (and up) Applications, you may be want to install phpredis to test your Application in a real life environment using phpredis instead of predis (which is not getting any activity since a while at the time of writing).
You can install phpredis by running the following commands (found in this SO answer):
git clone https://www.github.com/phpredis/phpredis.git cd phpredis phpize && ./configure && make && sudo make install
After this, you need to enable the extension by adding
extension="redis.so" to your used php.ini file:
code /usr/local/etc/php/$(php --version | head -n 1 | cut -d " " -f 2 | cut -d "." -f 1,2)/php.ini
After a restart of php (and if you have laravel/valet) you should be able to using phpredis.
