How get geolocation info outside of pc "LocalHost"? - php

Question

I want obtain some geolocation informations using a external service (website service), but this works fine only in my pc (localhost using WampServer http client); already when my php file is transfered for a remote host (pc), it fails for get these information. Already tried several services of hosts, but still without success.
PS: My reference of website was http://ip-api.com/.
Here is my code:
$ip = $_REQUEST['REMOTE_ADDR'];
$query = #unserialize(file_get_contents('http://ip-api.com/php/'.$ip));
if($query && $query['status'] == 'success') {
$regiao = $query['regionName'];
$cidade = $query['city'];
$isp = $query['isp'];
$sigla_regiao = $query['region'];
}
else {
echo '';
}
So, someone have some ideia why this api don't works in a remote host?
Thanks in advance.

Answer 1

According to the error you posted, the file_get_contents function is not able to create a connection to the remote host. It may be that the access to remote resources is disabled for certain functions.
You can try to access the remote URL with cURL:
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, "http://ip-api.com/php" . $ipAddr);
curl_setopt ($curl, CURLOPT_RETURNTRANSFER, 1);
$content = curl_exec ($curl);
curl_close ($curl);
if (curl_errno($curl))
throw new \Exception(sprintf("Connection error %s: %s", curl_errno($curl), curl_error($curl)));
print_r(unserialize($content));

If you're interested in another provider, you can use the services of https://geoip-db.com
A working JSON example:
<?php
$json = file_get_contents('https://geoip-db.com/json');
$data = json_decode($json);
print $data->country_code . '<br>';
print $data->country_name . '<br>';
print $data->state . '<br>';
print $data->city . '<br>';
print $data->postal . '<br>';
print $data->latitude . '<br>';
print $data->longitude . '<br>';
print $data->IPv4 . '<br>';
?>
Or a JSONP callback with php:
<?php
$jsonp = file_get_contents('https://geoip-db.com/jsonp');
$data = jsonp_decode($jsonp);
print $data->country_code . '<br>';
print $data->country_name . '<br>';
print $data->state . '<br>';
print $data->city . '<br>';
print $data->postal . '<br>';
print $data->latitude . '<br>';
print $data->longitude . '<br>';
print $data->IPv4 . '<br>';
// Strip callback function name and parenthesis
function jsonp_decode($jsonp) {
if($jsonp[0] !== '[' && $jsonp[0] !== '{') {
$jsonp = substr($jsonp, strpos($jsonp, '('));
}
return json_decode(trim($jsonp,'();'));
}
?>
