PHP: No response when try to proceed a json string

Question

PS: This code is modified from Getting visitors country from their IP

I try to use the ipdata service from https://api.ipdata.co/ but when I try to use PHP to decode the json, nothing happened. Even when I try to print the api response out. Can anyone help me lol..

The php code:

function ip_info($ip = NULL, $purpose = "location", $deep_detect = TRUE) {
$output = NULL;
if (filter_var($ip, FILTER_VALIDATE_IP) === FALSE) {
    $ip = $_SERVER["REMOTE_ADDR"];
    if ($deep_detect) {
        if (filter_var(@$_SERVER['HTTP_X_FORWARDED_FOR'], FILTER_VALIDATE_IP))
            $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
        if (filter_var(@$_SERVER['HTTP_CLIENT_IP'], FILTER_VALIDATE_IP))
            $ip = $_SERVER['HTTP_CLIENT_IP'];
    } else {
        echo "error [2]";
    }
} else {
    echo "error [1]";
}
$rdata = file_get_contents("http://api.ipdata.co/" . $ip);
echo $rdata;
$ipdat = @json_decode($rdata);
echo $ipdat;
$output = @$ipdat->country_code;
return $output;
}

echo ip_info("Visitor", "country");

Try `https` instead of `http` as your protocol in the URL, just as a sanity check :) — B. Fleming, Dec 17 '17 at 01:42
Thanks for commenting! I tried to use http instead of https, but it doesn't seems to be working loll... I also tried to print out the url, it will prints the url, but nothing else... — imgg, Dec 17 '17 at 01:46
Is this your actual code? `echo ip_info("Visitor", "country");` — miknik, Dec 17 '17 at 01:47
I also tried adding error_reporting(E_ALL) but it is not working either. — imgg, Dec 17 '17 at 01:47
Well it's a little buggy, throws a few errors but your code works for me. Have you got fopen wrappers enabled in your php config? — miknik, Dec 17 '17 at 02:01
Hi imgg we had a small outage yesterday morning which might've why you got this. — Jonathan, Dec 18 '17 at 13:57

Try this

function ip_info($ip = NULL, $deep_detect = TRUE) {
    if ($ip == NULL || !filter_var($ip, FILTER_VALIDATE_IP)) {
        $ip = $_SERVER["REMOTE_ADDR"];
        if ($deep_detect) {
            if (filter_var(@$_SERVER['HTTP_X_FORWARDED_FOR'], FILTER_VALIDATE_IP)){
                $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
            }
            if (filter_var(@$_SERVER['HTTP_CLIENT_IP'], FILTER_VALIDATE_IP)){
                $ip = $_SERVER['HTTP_CLIENT_IP'];
            }
        }
    }

    $ch = curl_init("http://ip-api.com/json/".$ip);
    curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 5);
    $result = curl_exec($ch);
    curl_close($ch);
    $result = json_decode($result, true);

    if($result['status'] == "fail"){
        $result = FALSE; /* If an Error has come back, you can use $result['message'] to get why. */
    } 
    else { $result =  $result['countryCode']; } // If Sucess
    return $result;
}

The API you were using was slow and also using file_get_contents is not a good idea. — Noah, Dec 17 '17 at 02:22
Not a problem Have fun with it! Check the API URL and see what other things you can get. http://ip-api.com/json/ — Noah, Dec 17 '17 at 02:37
@imgg we had an outage yesterday morning which might'be been why you got this. I'm able to run the code in the example from the question you linked to and the php test code on our docs page ipdata.co/docs.html — Jonathan, Dec 18 '17 at 13:59

We had an outage yesterday morning that might've caused this. I've tested the following code and it works for me. Let me know if you have any issues.

function ip_info($ip = NULL, $deep_detect = TRUE) {
    if ($ip == NULL || !filter_var($ip, FILTER_VALIDATE_IP)) {
        $ip = $_SERVER["REMOTE_ADDR"];
        if ($deep_detect) {
            if (filter_var(@$_SERVER['HTTP_X_FORWARDED_FOR'], FILTER_VALIDATE_IP)){
                $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
            }
            if (filter_var(@$_SERVER['HTTP_CLIENT_IP'], FILTER_VALIDATE_IP)){
                $ip = $_SERVER['HTTP_CLIENT_IP'];
            }
        }
    }

    $ch = curl_init("https://api.ipdata.co/".$ip);
    curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 5);
    $result = curl_exec($ch);
    curl_close($ch);
    $result = json_decode($result, true);

    $result =  $result['country_code'];
    return $result;
}
var_dump(ip_info('1.1.1.1'));
//string(2) "AU"

interesting...! never mind, i have been able to use the ipdata now. thanks for replying! — imgg, Dec 26 '17 at 06:01
