Install PHP PECL modules

Modules are defined in bootstrapper's scope via pecl_extensions var.

bash

# Get defined PECL modules
cpcmd scope:get cp.bootstrapper pecl_extensions
# Define new PECL modules
cpcmd scope:set cp.bootstrapper pecl_extensions '[imagick,igbinary,redis,memcached]'

After setting pecl_extensions to be installed, you should actually install them.

bash

# Build all modules
upcp -sb php/install-extensions
# Build all modules for Multi-PHP installs
cd /usr/local/apnscp/resources/playbooks
ansible-playbook bootstrap.yml --tags=php/install-extensions --extra-vars=php_version=7.4 --extra-vars=multiphp_build=true
