在CodeIgniter中使用Curl：如何使用post方法发送数据

Question

Not going to succeed when trying to send data using post method. Never used it before.

This is code of executing curl:

$url = LICENSE_URL."validate_system_key/validate_key/";
        //url-ify the data for the POST
        $data['system_key']='A8Z0-X1N7-S1V2-Y1I5';
        $data['domain']='http://example.com';
            $fields_string = '';
            foreach($data as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
            $fields_string = rtrim($fields_string,'&');


            //open connection
            $ch = curl_init();

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

            curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,10); # timeout after 10 seconds, you can increase it
           //curl_setopt($ch,CURLOPT_HEADER,false);
            curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);  # Set curl to return the data instead of printing it to the browser.

            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

            //execute post
            $result = curl_exec($ch);

            //close connection
            curl_close($ch);
          $result=json_decode($result,TRUE);

And this is the Code On Client Url:

public function validate_key(){
        $system_key=$_POST['system_key'];
        $domain=$_POST['domain'];
        $result['error']=3;
        echo json_encode($result);
}

Note: When I am not using POST method (sending data through url) evrything is fine. Its all about POST method, not getting the mistake! Any kind of help will be appreciated! Thanks.

Use array instead of String in data passed to string like below:

foreach($data as $key=>$value) { 
 $data[$key] = $value;
}
curl_setopt($ch,CURLOPT_POSTFIELDS,$data);

I hope this will work.
