Examples

$this->load->library('curl'); 

Simple calls

These do it all in one line of code to make life easy. They return the body of the page, or FALSE on fail.

// Simple call to remote URL
echo $this->curl->simple_get('http://example.com/');

// Simple call to CI URI
$this->curl->simple_post('controller/method', array('foo'=>'bar'));

// Set advanced options in simple calls
// Can use any of these flags http://uk3.php.net/manual/en/function.curl-setopt.php

$this->curl->simple_get('http://example.com', array(CURLOPT_PORT => 8080));
$this->curl->simple_post('http://example.com', array('foo'=>'bar'), array(CURLOPT_BUFFERSIZE => 10)); 

Advanced calls

These methods allow you to build a more complex request.

// Start session (also wipes existing/previous sessions)
$this->curl->create('http://example.com/');

// Option & Options
$this->curl->option(CURLOPT_BUFFERSIZE, 10);
$this->curl->options(array(CURLOPT_BUFFERSIZE => 10));

// More human looking options
$this->curl->option('buffersize', 10);

// Login to HTTP user authentication
$this->curl->http_login('username', 'password');

// Post - If you do not use post, it will just run a GET request
$post = array('foo'=>'bar');
$this->curl->post($post);

// Cookies - If you do not use post, it will just run a GET request
$vars = array('foo'=>'bar');
$this->curl->set_cookies($vars);

// Proxy - Request the page through a proxy server
// Port is optional, defaults to 80
$this->curl->proxy('http://example.com', 1080);
$this->curl->proxy('http://example.com');

// Proxy login
$this->curl->proxy_login('username', 'password');

// Execute - returns responce
echo $this->curl->execute();

// Debug data ------------------------------------------------

// Errors
$this->curl->error_code; // int
$this->curl->error_string;

// Information
$this->curl->info; // array
