CakePHP 5 uses zend.assertions = 1 for development so if you have production and test environments on your server you need separate instance of php-fpm so you can run one with zend.assertions = 1 for development and the other zend.assertions = -1 for production
The following is done on Ubuntu 24.04 LTS
Copy the default php8.3-fpm.service file to a new name and location
1 | cp /etc/systemd/system/multi-user.target.wants/php8.3-fpm.service /etc/systemd/system/php8.3-fpm-test.service |
Copy the default php.ini to a create a separate php.ini for the new php-fpm service
1 | cp /etc/php/8.3/fpm/php.ini /etc/php/8.3/fpm/php-test.ini |
Modify the contents of the service file to use the different php-test.ini and a new socket

Modify the contents of the php-test.ini e.g. add stuff you want for a dev setup for example you can up the memory or enable assertions and xdebug.

Create a pool directory for the new php-fpm instance
1 | sudo mkdir /etc/php/8.3/fpm/pool-test.d |
Create a pool file /etc/php/8.3/fpm/poot-test.d/www-test.conf (notice how it is using the different socket and you could change the user/group to be some thing other than www-data too)

Configure nginx to use the now separate default and 'test' php-fpm instances. In this example the /live location uses the default php8.3-fpm service and the /test location uses the php8.3-fpm-test service

Enable the service
1 | sudo systemctl enable php8.3-fpm-test.service |
You should now have separate php-fpm services with separate php.ini files you can tweak as you like
