PHP CURL to CodeIgniter controller

here's my code:

<?php
    $url = 'http://localhost:2304/index.php/testproj/files/add/';

    $name = "test";
    $fields = array(
            'name'=>urlencode($name)
    );

    $fields_string = "";
    foreach($fields as $key=>$value) {
        $fields_string .= $key.'='.$value.'&';
    }
    rtrim($fields_string,'&');

//open connection
    $ch = curl_init();

//set the url, number of POST vars, POST data
    curl_setopt($ch,CURLOPT_URL,$url);
    curl_setopt($ch,CURLOPT_POST,count($fields));
    curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

//execute post
    开发者_JAVA技巧$result = curl_exec($ch);
    var_dump($result);
//close connection
    curl_close($ch);

?>

I am trying to send post data to a CodeIgniter controller. I decided to use CURL to do the job. however, it doesn't work, when I put "blah" in my controller, it doesn't return anything. When I access the URL directly, it shows "blah".

You could use my Curl library:

$this->load->library('curl');
$result = $this->curl->simple_get('http://example.com/');
var_dump($result);

Try adding this into options

$ch = curl_init();
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 

Edit 1

add this

curl_setopt($ch, CURLOPT_HEADER, 1);
// and post the result of $result
