VERSION HISTORY AND DESCRIPTION

[from pre-beta version] When i develop some project, i need to have a simple way to call another controller, or even an external resource (ex. api from google). I create a simple cURL class to do that. This is the (almost) stable version of that, this enough for my needs. I'll take it to higher level, as soon as i had a long holiday from my work.

For now, enjoy!

// Simple way to use this library
// In any controller, put this line...
...
$this->load->library('proxy');
$this->proxy->site('http://codeigniter.com',TRUE);
...

// Above example will give you rendered page of CodeIgniter site, if you didn't want
// to render it directly, or it was a json which you want to save to var, simply do this...
...
$this->load->library('proxy');
$json_var = $this->proxy->site('http://ip2country.sourceforge.net/ip2c.php?ip='.$ip.'&format=JSON');
...

// To call your controller (maybe in some situation, you need it instead use redirect() function)
...
$this->load->library('proxy');
$this->proxy->controller('your_target_controller_name/target_function/some_id');
...

============================================================================ [from version 1.0.5] Fixing URL Schema Builder bug for multiple call

[from version 1.0.6] All General HTTP Method Support(All old feature still there):

HTTP (GET, POST, PUT, DELETE), REST and HTTP Authentfication.

/* [USAGE] Basic http structure : */
/* $this->proxy->http($method, $destination_url, $request_parameter, $request_header_parameter); */
// $method is HTTP method : 'GET', 'POST', 'PUT', 'DELETE'
// $destination_url is the full url. Proxy lib will automaticly find the host, so include the full url, not only the domain
// $request_parameter is array of your GET, POST, PUT or DELETE parameter. eg : array('id' => 1);
// $request_header_parameter is array of custom HTTP header, it can be API key, oauth stuff, or any of your needs. 
//     PS : For Basic HTTP Authorization, use : array('auth' => 'username:password'), as params

$this->load->library('proxy');
// An easy example performing basic 'POST' and get the result rendered. 
echo $this->proxy->http('POST', 'http://somesite.com/login.php', array('username' => 'username', 'password' => 'password'));
// Perform an API Call? here you go...
// An example of GET
$username = 'taufanaditya';
$tweets = $this->proxy->http('GET', 'http://twitter.com/statuses/user_timeline/'.$username.'.json');
// Already have your own REST, now you can perform a Rest Client Call, without cURL at all!
// An example of POST, with Basic HTTP Authentification
echo $this->proxy->http('POST', 'api.yourdomain.com/api/users', array('id' => 10, 'name' => 'Changed via Proxy'), array('auth' => 'username:password'));
// An example of PUT, with custom HTTP header (like API Key, or anything else)
$new_user = array(
    'name'             => 'John Doe',
    'username'         => 'johndoe',
    'email'            => 'johndoe@otherworlds.com',
    'password'         => 'secret',
    'confirm_password' => 'secret',
);
echo $this->proxy->http('PUT','api.yourdomain.com/api/users', $new_user, array('X-API-KEY' => 'fooandbarnotencrypted'));

============================================================================ [from version 1.0.7] Set HTTP Parameter Support(All old feature still there):

// An example of DELETE, with custom HTTP header (like API Key, or anything else) by setting HTTP params (it should be an array!)
$this->proxy->set_http(array(
        'head' => array('X-API-KEY' => 'fooandbarnotencrypted'),
        'body' => array('id' => 1),
    )
);
// Now you have a simple and short line
echo $this->proxy->http('DELETE','api.yourdomain.com/api/users');
