Question

I have a simple PHP function on a friend server which I’ve checked and has PHP CURL enabled.

The function is:

function sw_fetch_code($apikey='',$email=''){

 $url = "http://www.domain.com/xxx/api.php?getcode=1&apikey=".$apikey."&email=".$email."";


        $ch = curl_init();
 curl_setopt($ch, CURLOPT_URL, $url);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($ch, CURLOPT_HEADER, 1); 
 $result = curl_exec($ch);

 curl_close($ch);

 $obj = json_decode($result);  

 if(!empty($obj)){
  if($obj->status == 200){

   return $obj->code;

  }else{
   return $obj->status;
  }
 }

}

As you can see this is very simple and I’ve tested it and works on localhost and internal to my own server. The url returns as expected. However it just doesn’t give any response when this function is called on my friends server.

Any ideas what could cause this?

Answer 1

First :
check from the “friend” server if the URL works, as you donot have POST params, you can check with the exact query and get expected results. See if you can get the results on the browser on the friend server. If you don’t have a GUI try wget on the command line. See if you get results. If you do go to next step, if you don’t cURL isn’t the problem. “friend server” isn’t able to see your domain. Could be network issue / hosts etc .. (more on that if its the case)

Second:
If you see results on step 1. Try this and see if you get anything:

$handle = fopen($url, "rb");
    $contents = '';
while (!feof($handle)) {
    $contents .= fread($handle,1024);
}

If you get response to this, then there is something wrong with cURL.
