Is there a way to change the two famous PHP variables post_max_size and upload_max_filesize in php.ini in a version-agnostic way with Ansible?

I didn't find any literature covering this and it seems wired to me because no company, let alone mega company will allow just the default 2M limit value of these two variables (which is prevalent since PHP was born, I think).

Ok. This got me intrigued, and here is what I came up with:

---

- hosts: all 

  become: yes 



  tasks:

    - name: Get path to php.ini

      find:

        paths: /etc/php

        file_type: directory

        recurse: no

      register: ini_path



    - name: Update php.ini post_max_size

      replace:

        dest: "{{ ini_path.files[0].path }}/apache2/php.ini"

        regexp: '^post_max_size.*$'

        replace: 'post_max_size = 20M'

        backup: yes 



    - name: Update php.ini upload_max_filesize

      replace:

        dest: "{{ ini_path.files[0].path }}/apache2/php.ini"

        regexp: '^upload_max_filesize.*$'

        replace: 'upload_max_filesize = 20M'

        backup: yes 

The first thing I do is use the find module to determine which version of php we are running, and of course registering that result into ini_path. This works because the only directory under /etc/php is the directory with the actual version number:

ls /etc/php/

7.2

Since the registered result is a python dictionary, I later combine the result with the complete path to php_ini:
"{{ ini_path.files[0].path }}/apache2/php.ini"

This way we can use the playbook despite not knowing beforehand which version of php we are running (within reason, we have to use apache2!).

Execution against my test server (Ubuntu 18) looks like this:

ansible-playbook update_phpini.yml -i "192.168.1.11," -kK

In a production environment, you could do more test, and use set_fact to assign the path to a variable early on. This is just a POC.

Also, of course adjust the file sizes to your liking!!!
