CodeIgniter-cURL is a CodeIgniter library which makes it easy to do simple cURL requests and makes more complicated cURL requests easier too.
//load the Curl library $this->load->library('Curl'); //Request using POST Method $url = 'http://postexample.com/json.php'; echo $this->curl->simple_post($url, false, array(CURLOPT_USERAGENT => true)); //Request using GET Method $get_url = http://getexample.com/json.php; echo $this->curl->simple_get($get_url, false, array(CURLOPT_USERAGENT => true));It is very important to set CURLOPT_USERAGENT, otherwise many servers may refuse your request if you don't pass user agent.
//PHP version, you can put anyvalue for CURLOPT_USERAGENT, but it shouldn't be empty or blank. curl_setopt($ch, CURLOPT_USERAGENT , "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)");I tried without setting CURLOPT_USERAGENT in GOOGLE CHROME, it didn't worked. I spent more than 4 hours to find a solution, why it is not returning the result. Finally, I found this post http://www.silverphp.com/php-curl-function-for-post-and-get-request.html and try with my luck. And it worked. :)
