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
