Running via the CLI
###################
As well as calling an applications :doc:`Controllers <./controllers>`
via the URL in a browser they can also be loaded via the command-line
interface (CLI).
- `What is the CLI? <#what>`_
- `Why use this method? <#why>`_
- `How does it work? <#how>`_
What is the CLI?
================
The command-line interface is a text-based method of interacting with
computers. For more information, check the `Wikipedia
article <http://en.wikipedia.org/wiki/Command-line_interface>`_.
Why run via the command-line?
=============================
There are many reasons for running CodeIgniter from the command-line,
but they are not always obvious.
- Run your cron-jobs without needing to use wget or curl
- Make your cron-jobs inaccessible from being loaded in the URL by
checking for ``$this->input->is_cli_request()``
- Make interactive "tasks" that can do things like set permissions,
prune cache folders, run backups, etc.
- Integrate with other applications in other languages. For example, a
random C++ script could call one command and run code in your models!
Let's try it: Hello World!
==========================
Let's create a simple controller so you can see it in action. Using your
text editor, create a file called tools.php, and put the following code
in it:
<?php class Tools extends CI_Controller { public function message($to =
'World') { echo "Hello {$to}!".PHP_EOL; } } ?>
Then save the file to your application/controllers/ folder.
Now normally you would visit the your site using a URL similar to this::
example.com/index.php/tools/message/to
Instead, we are going to open Terminal in Mac/Lunix or go to Run > "cmd"
in Windows and navigate to our CodeIgniter project.
$ cd /path/to/project;
$ php index.php tools message
If you did it right, you should see Hello World!.
$ php index.php tools message "John Smith"
Here we are passing it a argument in the same way that URL parameters
work. "John Smith" is passed as a argument and output is: Hello John
Smith!.
That's it!
==========
That, in a nutshell, is all there is to know about controllers on the
command line. Remember that this is just a normal controller, so routing
and _remap works fine.
