Has this idea been explored?
I have started writing a set of PHP classes to be located
here https://github.com/Appdynamics/ansible-php. The idea is to, as part of
the task, if the module is determined to be written in PHP (check shebang),
then copy this library over to the right place. The PHP process would be
called with a custom INI file that would have include_path set properly.
The module then only needs a short amount of code to start with just like a
Python-based Ansible module. The primary use case would be with websites
written in PHP that need easier interfacing than using Python. Typical site
types include Drupal, WordPress, and sites written with the Syfmony 2
framework. While all of these have command line helpers (drush and wp-cli,
Symfony 2 console), it is quite useless to have 'changed: true' every time
you run a command (via command or shell modules) when nothing has really
changed.
Example module (the only boilerplate is the first 3 lines):
#!/usr/bin/env php
<?php
require 'Ansible.php'; // class auto-loading file or just includes all of
them
$module = new AnsibleModule(
array('dir' => array('type' => 'directory'), 'set_mode' => array('type'
=> 'bool'), 'mode' => array('choices' => array('production', 'staging',
'dev'))
);
$include = $module->params['dir'] . DIRECTORY_SEPARATOR . 'somecode.inc';
$should_set_mode = $module->params['set_mode']; // === true or false,
because of the type key in the argument specification
$target_mode = $module->params['mode'];
$changed = false;
// Here, require the PHP code at the $dir argument, and set the application
to the mode if $should_set_mode === true
// If an error occurs, call $module->failJson(); optionally with an array
of data
$module->exitJson(array('changed' => $changed));
One area of concern is compatibility, so I am avoiding using new features
such as namespaces. Perhaps the oldest version to go down to is PHP 5.2
(influenced mostly by CodeIgniter's standards).
If this were to be seriously explored and merged into Ansible core, I would
like to know where these files would go. The lib/ directory seems the most
likely place.
