Enabled pi command line

[linzongshu]

Yii provide a command controller for developers to easily execute php script in server end. Just like:

./yii {controller}/{action}  {param1} {param2}

I look deep into Zend code, and find that Zend also provide a console mode, then we can extend its function and provides a convenient way for developers to develop command line action just like yii does, for example:

www/pi {module}/{controller}/{action} {param1}  {param2} ...

This will be very great for developers to execute script as well as use Pi api.

The function has been achieved in commit 4b552a6

Then how to start a command controller, please following this brief document:

1. Change the php install path:

Open the www/pi file, and change the php file path in the first line to your php installed path. for example, your php installed in /data/lib/php, the first line should be changed to:

#!/usr/bin/env /data/lib/php/bin/php

Or leaves this file unchanged, and execute the command line by:

/data/php/bin/php  www/pi  {module}/{controller}/{action} {params1}  {params2}

1. Create a command controller:

Create a 'Command' folder under src/Controller folder of your module.

Add a new controller, for example TestController, and add following codes:

<?php
namespace Module\Merchant\Controller\Command;

use Pi;
use Pi\Mvc\Controller\CommandController;

class TestController extends CommandController
{
    public function indexAction($param1, $param2)
    {
        $module = $this->getModule();
        $model   = $this->getModel('test');
        ...
    }
}

And do what you want to do like you do with front/admin actions. Note that you can output result just with
var_dump and echo other than $this->view()->assign().

@voltan
I have spent too much time on my work these times and didn't care much about Pi develop. But it also help me to find things should to be done of the Pi. Such as supporting master-slave mysql, some security issues.
I will continue to focus on these issues and fix them.
