curl is not working in Yii - php

Question

when i am using curl in my core php file it's working fine for me and getting expected result also... my core php code is...
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, "http://stage.auth.stunnerweb.com/index.php?r=site/getUser");
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($curl);
echo $data; //here i am getting respond proper
here in above i am making call to getUser function and i am getting respond from that function...
but now my problem is when i am using this same code in my any Yii controller (tried to use it in SiteController & Controller) but it's not working...
public function beforeAction()
{
if(!Yii::app()->user->isGuest)
{
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL ,"http://stage.auth.stunnerweb.com/index.php?r=site/kalpit");
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($curl);
echo $data;
}
else
return true;
}
in yii can't we use curl like this?
Can you please suggest me how to use curl in yii?
Thanks in advance

Answer 1

Better use yii-curl
Setup instructions
Place Curl.php into protected/extensions folder of your project
in main.php, add the following to 'components':
php
'curl' => array(
'class' => 'ext.Curl',
'options' => array(/.. additional curl options ../)
);
Usage
to GET a page with default params
php
$output = Yii::app()->curl->get($url, $params);
// output will contain the result of the query
// $params - query that'll be appended to the url
to POST data to a page
php
$output = Yii::app()->curl->post($url, $data);
// $data - data that will be POSTed
to PUT data
php
$output = Yii::app()->curl->put($url, $data, $params);
// $data - data that will be sent in the body of the PUT
to set options before GET or POST or PUT
php
$output = Yii::app()->curl->setOption($name, $value)->get($url, $params);
// $name & $value - CURL options
$output = Yii::app()->curl->setOptions(array($name => $value))->get($get, $params);
// pass key value pairs containing the CURL options

You are running your code inside a beforeAction() method which is not supposed to render any data at all. On top of that, you do not let the method return anything if the current user is a guest. Please read the API docs concerning this.
