i start learning ansible and i try to install PHP and php extensions.
I have a file where i declare my php versions and php extensions and its look like:

    php:

  versions:

    - 7.2:

      - cli

      - fpm

      - curl

      - mysql

      - pdo

      - zip

      - xml

      - gd

      - mbstring

      - tokenizer

      - ctype

      - json

    - 7.3:

      - cli

      - fpm

      - curl

      - mysql

      - pdo

      - zip

      - xml

      - gd

      - mbstring

      - tokenizer

      - ctype

      - json

I am doing that because i wanna learning ansible, and also for flexibility and to install different extensions for every php versions.

I try to debug my code using this (this is under tasks section in my playbook.yml file)

- name: DEBUG ANSIBLE PLAYBOOK

  debug:

    msg: The key is - {{ item.keys() | first }} The item is "{{ item[item.keys() | first] }}"

  loop: "{{ php.versions }}"

  loop_control:

    loop_var: item

I get this output:

TASK [DEBUG ANSIBLE PLAYBOOK] 

ok: [127.0.0.1] => (item={7.2: [u'cli', u'fpm', u'curl', u'mysql', u'pdo', u'zip', u'xml', u'gd', u'mbstring', u'tokenizer', u'ctype', u'json']}) => {

    "msg": "The key is - 7.2 The item is "[u'cli', u'fpm', u'curl', u'mysql', u'pdo', u'zip', u'xml', u'gd', u'mbstring', u'tokenizer', u'ctype', u'json']""

}

ok: [127.0.0.1] => (item={7.3: [u'cli', u'fpm', u'curl', u'mysql', u'pdo', u'zip', u'xml', u'gd', u'mbstring', u'tokenizer', u'ctype', u'json']}) => {

    "msg": "The key is - 7.3 The item is "[u'cli', u'fpm', u'curl', u'mysql', u'pdo', u'zip', u'xml', u'gd', u'mbstring', u'tokenizer', u'ctype', u'json']""

}

And i try to install PHP using this task:

- name: Install PHP

  package:

    pkg: php{{ item.keys() | first }}-{{ item[item.keys() | first] }}

    state: latest

  loop: "{{ php.versions }}"

  loop_control:

    loop_var: item

  notify: Restart Nginx

But is not working because item[item.keys() | first] is an array and i don't know how to loop again to receive cli, fpt instead of an array.

I study ansible from 3 days, and i really don't understand how can loop more times. I search on the web, i read documentation, but i don't understand

https://docs.ansible.com/ansible/2.4/playbooks_loops.html

If someone can explain, i will appreciate very much!

Ok, after i research a lot i found a solution

- name: Install PHP && Packages

  become: true

  package:

    pkg: php{{ item.0.version }}-{{ item.1 }}

    state: latest

  with_subelements:

    - "{{ php }}"

    - libs

  notify: Restart Nginx

This work for me. Also, i change my array:

php:

  - version: 7.2

    libs:

      - cli

      - fpm

      - curl

      - mysql

      - pdo

      - zip

      - xml

      - gd

      - mbstring

      - tokenizer

      - ctype

      - json

  - version: 7.3

    libs:

      - cli

      - fpm

      - curl

      - mysql

      - pdo

      - zip

      - xml

      - gd

      - mbstring

      - tokenizer

      - ctype

      - json

I let this here, maybe someone will found this helpful.

An option would be to use include_tasks. See the hint below.

tasks:

  - include_tasks: test.yml

    loop: "{{ php.versions }}"

    loop_control:

      loop_var: php_ver

.

> cat test.yml

- debug: msg="{{ lookup('dict', php_ver).key }}"

- debug: msg="{{ item }}"

  loop: "{{ lookup('dict', php_ver).value }}"

Here is the playbook

> cat test-31.yml

---

- hosts: localhost

  gather_facts: no

  vars:

    php:

      versions:

        - 7.2:

            - cli

            - fpm

            - curl

            - mysql

            - pdo

            - zip

            - xml

            - gd

            - mbstring

            - tokenizer

            - ctype

            - json

        - 7.3:

            - cli

            - fpm

            - curl

            - mysql

            - pdo

            - zip

            - xml

            - gd

            - mbstring

            - tokenizer

            - ctype

            - json

  tasks:

    - include_tasks: test.yml

      loop: "{{ php.versions }}"

      loop_control:

        loop_var: php_ver

Here is the output
